Wrong time on virtual machine

Hello,
I'm running Windows 2003 Standard virtual machines under a Windows 2008 Datacenter Hyper-V Server. The system time of all of my virtual machines is 3 hours later than the time of my physical host.
When I try to change the time on my VMs, it resets itself back to the wrong time after a few seconds, and I get this message in the System log:
Event Type: Information
Event Source: W32Time
Event Category: None
Event ID: 35
Description:
The time service is now synchronizing the system time with the time source VM IC Time Synchronization Provider.
Any ideas on what might be causing this?
Thanks,
Stephen
Are any of your DCs on physical boxes? If they are then set them up to pull time from pool.ntp.org. Then set up your hosts and guests to pull from that DC. Allow firewall exceptions for NTP inbound on that DC.
If all DCs are VMs then set up one of the physical hosts to poll pool.ntp.org for time and then set the VMs to poll the host. Again set the firewall accordingly.
http://blog.mpecsinc.ca/2011/01/hyper-v-preparing-high-load-vm-for-time.html
We have had a lot of pain over the time skew situation for VMs.
The above methods work for us. In some cases we drop in an HP MicroServer with Win2K8 R2 running as a DC and set it up to poll pool.ntp.org and then have all VMs poll it for time.
The problem has to do with the polling frequency needed as indicated in the blog post. Do that to ntp.org's servers and they will pass along the Kiss-Of-Death packets basically killing the ability to poll their servers for time.

Time was not correct on dc which is hyper-v virtual machine

My enviroment:
1 physical server dell R720
Role: Hyper-V host
OS: Windows 2008 R2 SP1
Domain: join to domain xx.com
1 virtual machine
Role: DC+DNS+DHCP
OS: Windows 2008 R2 SP1
Domain: xx.com (olny one dc)
Located on: this hyper-v host
Issue:
I found time of virtual machine (this only one dc) was slower than current time. At that moment, time on host machine also slower, and same as dc. When I manual adjust this time to correct. It would go wrong again.
Considering time sync rule of domain and hyper-v, I just unchecked 'Time Synchoniation' on hyper-v intergrate services. Howerver time was slower again after few days.
Could it be possible wrong on hyper-v host which join to domain??
So could you give me some suggestion for this? Thanks in advance.

Hi,
You should not need to disable Hyper-V time synchronization in order to use a different time synchronization source.
" if you are running a Domain Controller inside a virtual machine I would recommend that you leave Hyper-V time synchronization enabled but that you also setup an external time source. You can do this by going to this KB article:
http://support.microsoft.com/kb/816042 and following the steps outlined in the “Configuring the Windows Time service to use an external time source” section. "
Here is a grate article about time synchronization in hyper-v :

Transferring a virtual machine from one server to another

Hello --
I am going to be replacing the host system that currently has VMware server running with one virtual machine. The current system is a 32-bit Windows XP host, and the new system is a Windows 2008R2 64-bit server.
The current host gets backed up every night which includes the Virtual Hosts directory. I want to be able to transfer the virtual host from the current to the new system, and I wanted to know if there is anything in particular that needs to be done in order to accomplish this task?
Thanks.

Hello --
I went through the motions of starting the server, and this time I encountered an error message indicating VMWare could not access the lock file. My next step was to go the Virtual Machines/<server> directory, and removing the correct .lck file, which in this case had today's date. I then tried starting the virtual machine again, and this time it came up.
I am doing further testing on it, but it appears to be operating properly. This was accomplished without having to interact with any message box. Why would this have worked this time? Also, will I have to go through the motions of removing the lock file every time the virtual machine is brought down, or should this be a one-time occurrence?

Virtual Machine - high disk response time

Hi Everyone,
Got something strange happening in our lab at the moment and was wondering if anyone had experienced the same thing (and maybe has a solution).
Our lab environment in a nutshell:
2x Windows 2012 Hyper hosts cluster connected to a "home-made" SAN based on Windows 2012 iSCSI target.
Each Hyper-V host has two 1Gbps network cards to connect to the SAN via the Microsoft iSCSI initiator, with MPIO in load-balancing mode (least queue depth).
The SAN (Windows 2012 server with iSCSI target) has 4x 1Gbps cards, teamed two by two, so presenting two IP addresses used by each hosts to connect to it (via MPIO).
The disk subsystem on the Windows 2012 SAN is an external HP storage works with 25x HP 500 SATA disks, connected to the server via an INTEL RAID controller with 2x 240GB SSD caching enabled for read/write.
The iSCSI network is on a dedicated HP switch, with flow-control and jumbo frame enabled (tested ok).
Now the problem:
I've built a few virtual machines on the two hyper-v nodes and I'm getting very bad disk response time as soon as there is an increase in the disk traffic.
When the virtual server is doing very little, I get a normal 6-8ms, but I soon as I increase the traffic (by for example copying a big file, or installing an application), this figure shoots up to 200ms, 300ms and more!
So I first thought that it was my disk subsystem (and the SAN server), but while the spikes are happening within the virtual machine, the disks on the SAN Server are sitting at about 10ms, with some spikes to about 20ms (which is pretty good and what I would
expect to see within the VM because of the SSD cache).
I then thought it could be the network, but during those times of activity, the network does not get saturated at all. Barely 150Mbps to 200Mbps per link.
I even tried to disable MPIO and run everything across one Ethernet link, but still the same result.
Am I missing something here? doing something wrong? or is this expected behaviour?
Thank you,
Stephane

Hi,
VR38DETT is right, if you want to use more ISCSI bandwidth or redundancy you must use the MPIO method, Multipath I/O (MPIO) is a feature that provides support for using multiple
data paths to a storage device. Multipathing increases the availability of storage resources by providing path failover from a server or cluster to a storage subsystem.

Does Time Machine make complete backups of Virtual Machines?

I am new to the forums, so forgive me if this has been asked before.
I have a MacBook Pro and have VMWare Fusion 3 installed.
I have Windows 7 and XP installed as virtual machines, and use an external hard drive to back up into using Time Machine. I have been given conflicting information regarding the backups being created by Time Machine.
I have been told that I should use a Windows backup program such as Acronis to back up the Windows installations separately from the Mac backups on the separate hard drive.
Someone else has told me that if I use Time Machine, then the Windows installations will be backed up automatically, as the Windows installations are effectively folders and files within the Mac software.
Just to confuse things, I have read somewhere that Time Machine cannot back up Boot partitions of Windows installations, but I can't remember where I read this.
I don't want to lose my Windows installations through not understanding the backup capabilities of Time Machine, so I am hoping that someone here can advise me as to what the best course of action would be please.
Can I trust Time Machine to back everything up and to be able to restore my whole machine, including Windows installations, from a Time Machine backup, or do I need to back up the Windows virtual machines separately by using Acronis.
Thanks
Kevin

1. TM will not backup a Boot Camp Windows volume.
2. TM will backup a VM disc image every time it changes unless you have excluded it via TM's Exclude list.
3. If the VMs change often then TM will backup each change thus consuming large amounts of space on the backup drive which is not recommended. Thus, it's best to backup VMs separately from within Windows using a Windows backup utility.
4. TM will not backup individual files and folders of a VM disc image. It will only backup the entire disc image.

I have a domain with 2 DCs (both virtual machines) in different Hyper-V Hosts. Dose this case make any influence on the time sync?

As title,
I have a domain with 2 DCs (both virtual machines) in 2 different Hyper-V Hosts, and one of the perform as a PDC Emulator.
Dose this case make any influence on the time sync?
i.e. Both of the VMs sync with Hyper-V host, instead the other host should sync with the PDC Emulator?
I run w32tm command and get the following result:
C:\Users\Administrator.DOMAIN8>w32tm /query /computer:dc8.domain8.local /source
VM IC Time Synchronization Provider
C:\Users\Administrator.DOMAIN8>w32tm /query /computer:hpvzh05.domain8.local /source
VM IC Time Synchronization Provider
HPVZH05.domain8.local works as PDC server.
How can I make DC8 sync with HPVZH05?

Awesome!
It looks like your PDC is successfully pulling time from an external source. DC8 is not longer pulling from Hyper-V so that is good.
When you set a client to pull from a source ( and in this case DC8 is pulling from NT5DS, which tells it to pull from the PDC), and it CAN'T pull from that source, it will default to Local CMOS Clock. This is likely an easy fix.
First, check connectivity:
- Method one- Download Portqry and run this command: portqry -n HPVZH05 -p both -e 123 and see if the results say listening, or
- Method two- Run this command from DC8: w32tm /stripchart /computer:HPVZH05
If you get any kind of error using method two, it's a connectivity issue. (Maybe you have a firewall that's blocking access?)
The other cause of this, and probably more likely in your case, is that your PDC isn't properly advertising as a reliable time source, so DC8 isn't 'allowed' to pull from it.
Try running this command on your PDC: w32tm /config /reliable:yes
Then go restart time on your PDC, THEN DC8 again. (net stop w32time & net start w32time)

Cannot open 2 Virtual Machines at the same time to access the same Database

Folks,
Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.
The VM rac1 and rac2 run correctly when one of them is shutdown.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
While rac2 is running, I open rac1. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
While rac1 is running, I open rac2. But this error message comes up:
Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."
The 2 error messages are the same. This means I cannot open 2 VMs rac1 and rac2 at the same time. When we run RAC system, we have to open 2 machines or more than 2 machines at the same time so that all machines can access the same Database Server.
My question is:
Can any folk tell me how to have rac1 and rac2 run at the same time ?
Thanks.

You need to disable disk locking, which ordinarily is performed by the first VM to prevent any other VMs from corrupting your vmdk files via uncoordinated writes. You will have to shutdown both of your VMs and edit the *.vmx flat file for each, adding lines like the following (settings taken from workstation 6, but should be nearly identical settings for VM Player 3.x):
http://crosbysite.blogspot.com/2007/10/clustering-in-vmware-workstation-6.html
scsi1.sharedbus = "Virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
A few comments:
- your shared disks (scsi1) must be on a separate virtual scsi bus than the boot disk (scsi0), to allow setting the sharedbus flag as seen above.
- you must also ensure the cache parameters and unsynced writes settings are set to guarantee that all IO is immediately flushed to the vmdk file so the other VM can immediately access the latest version of data.

Virtual Machine crashing all the time: The previous system shutdown at a certain date was unexpected

Hello,
I've a build node that is constantly crashing and rebooting.

For instance regarding the machine latest crash I can see: The previous system shutdown at 10:24:57 on ‎27-‎02-‎2015 was unexpected.
But when I try to find some entry corresponding to that time i see none!

Hi JoseRebelo,
According to the title ,do you mean the host machine will reboot when we start the virtual machine and the virtual machine will crash or just the virtual will reboot ?Have you got a BSOD(Blue screen) ?
Did the issue occur before ?Have you installed any third party software recently ?
Please ensure the host machine has got the latest updates.
I suspect there may be a third party conflicts here.
Please try clean boot to have a troubleshoot .
How to perform a clean boot in Windows

If the issue occured recently ,we can try to perform a system restore to recover the machine to a previous point ot have a check.
Best regards

Trouble Accessing Virtual Machine After Time Machine Migration

I am hoping that someone else has run up against this problem and is able to help.
I recently purchased a new iMac. I upgraded to 8 GB of ram specifically because I have VMware Fusion and want to use it on my new machine.
I chose to migrate my entire old iMac to the new machine using my Time Machine backup.
VMware appears to have migrated successfully. I do not have any trouble accessing the application, but when I try to resume my only virtual machine, which is for Windows XP I get the following message:
VMware Fusion cannont connect to the virtual machine. Make sure you have rights to run the program and to access all directories it used and rights to access all directories for temporary files.
How do I resolve this problem?
Thanks in advance to anyone who is able to offer me a clue on how to overcome this.
If I can't access this machine it appears as if I will be able to create a new one. I would like to avoid having to do that if it is possible.

Captfred,
In that folder there is a virtual machine. It is called Windows XP Professional. So it is there. When I am in VMware Fusion I can see Windows Media Player, which is what I was probably accessing the last time I was in the machine, so it does appear to have backed up the virtual machine. I would expect it to because it is a part of a Mac application, VMware Fusion.
It appears to be an issue with permissions that I don't know how to solve.
I know there is a VMware forum, but I can't even figure out how to sign up for it the darned thing is so confusing. I can't seem to post to it no matter what I do.

Windows domain controller in a virtual machine: how dangerous is saving its state for a short period of time?

I have a Windows Server 2012 R2 virtualization cluster. All the hosts are connected to an external storage system, and virtual machines' files are stored on external volumes (CSVs). All the hosts and virtual machines are a part of the same AD domain
(mixed Windows Server 2012 RTM / 2008 R2 domain controllers). All the domain controllers are running in the virtual machines on the hosts of this cluster.
To prevent problems when all the hosts are turned off and then on simultaneously (for example, because of a power failure) all the domain controller VM files has been placed on local disks of the virtualization hosts (not on the Cluster Shared
Volumes). As Hyper-V services don't depend on other Windows Server services (except its networking components), it means that my domain controllers can always start, providing the virtualization host can start at all. However, it also means
that those DCs cannot be (quickly) migrated to other hosts while their current hosts are being rebooted. So if I need to reboot a virtualization host to install new updates, for example, I have to shut down the corresponding DC, reboot the host
and wait for the DC to finish cold boot and come back online. It means some interruption of service for our users, which, in turn, requires me to perform the reboots late in night.
The downtime can be significantly decreased by saving the state of the VM in which the DC is running. However, all the articles I've found on the Internet strongly recommend against it. I'm trying to understand why this recommendation was issued in the first
place. However, I'm unable to find a clear explanation. I've found some statements that saving state of a DC can cause serious AD replication problems because of tombstoning, and that the password of a DC computer account may be changed
while the DC itself stays in the saved state, which could prevent the DC from connecting to the domain after its state has been restored. However, those considerations are non-significant when we discuss a short-time
(5 to 10 minutes) saved state.
I work with AD and virtualization long time, and I fail to see any danger in saving state of a DC for several minutes. In my opinion, after its state has been restored it would simply replicate all the AD changes from other DCs, and that's all.
What's your opinion?

Hello,
as stated in "http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx"
Operational Considerations for Virtualized Domain Controllers
Domain controllers that are running on virtual machines have operational restrictions that do not apply to domain controllers that are running on physical machines. When you use a virtualized domain controller, there are some virtualization software features
and practices that you should not use:
Do not pause, stop, or store the
saved state of a domain controller
in a virtual machine for time periods longer than the tombstone lifetime of the forest and then resume from the paused or saved state.
This may sound as it is supported to store it for shorter times and use it.
BUT recommendation also from the Hyper-V Program manager in
http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx recommends against using them.
Also best practices

Setting up Time Sync when all domain controllers are virtual machines?

We have 2 existing server 2008 domain controllers on 2008 Hyper-V. We plan to set up a third domain controller in a new AD site at a remote site that will be Server 2012 R2 on 2012R2 Hyper-V.
PDC role DC is on one of the DCs in the original site.
How should time syncing be set?
From what I've read, all Hyper-V time synchronization between the virtual domain controllers and their Hyper-V host should be disabled.
So, do we set up the PDC virtual machine to sync to an external site source and then expect the other 3 domain controllers to automatically sync with the time of the PDC?
What happens with this process during a PDC reboot or if that PDC role domain controller becomes unavailable for any other reason? Does one of the other DCs then take over the role of domain time source even through they don't have access to the external
time source?
Should we also turn off Hyper-V time syncing for every Hyper-V guest that is a member of our domain (since they should also be getting their time from a domain controller) or only turn off the Hyper-V time sync for the domain controllers alone?

Simply make sure that time sync is disabled on your Hyper-V VM. For time configuration in AD domain, I have documented that here: http://social.technet.microsoft.com/wiki/contents/articles/18573.time-synchronization-in-active-directory-forests.aspx

They don't take over the role of PDC. The downtime of your PDC should not take a long time. That is why it is important to regularly monitor the health status of your DCs using SCOM or third party tools. The one I usually recommend is
Lepide Auditor - Active Directory: http://www.lepide.com/lepideauditor/active-directory.html. The solution allows you also to trackchanges
in your AD domain.
Should we also turn off Hyper-V time syncing for every Hyper-V guest that is a member of our domain
(since they should also be getting their time from a domain controller) or only turn off the Hyper-V time sync for the domain controllers alone?
I would recommend turning off the Hyper-V time sync on all your Hyper-V VMs that are domain-joined.

I cant start 2 Virtual machines at the same time in a Hyper-V enabled machine

Hi,
I have installed Windows 2008 Enterprise edition. Updated all patched from windows updated. Add the Hyper-V role and installed Windows 2003 in one Virtual Machine and Windows 2008 in another. After the first VM installation itself i had the problem as the below error was coming ibn.
I has to shutdown the Windows 2003 to install Windows 2008.
Now i can only run 1 OS at a time. Shut down 1 to start the other

I renamed them,Reinstalled OS, Created a new set of vm's after the first i get the error
It works fine if i stop 1 vm and install the other or stop 1 and start the other...Running both at the same time is the problem

Is Time Machine dealing with Fusion virtual machines differently now?

I have discovered and others have noted that TM backs up Fusion VMs as a single file. For me, this has been roughly 32GB a pop, chewing up my 500GB TM target volume breathtakingly quickly. Suddenly, however, changes within the VM are requiring only about 7.6GB per TM back-up, roughly one-quarter of the previous amount. Does anyone know what's going on here? I downloaded the usual monthly bushel of Windows automatic updates (security, stability, enhancements, etc.) yesterday for my Vista Ultimate guest VM; could these somehow have made the TM process for a Fusion VM more efficient? This seems too good to be true!

All --
The most knowlegeable VMware employee at the Fusion booth at Macworld (two other VMware employees there did not know) told me definitively that Fusion virtual machines are no longer being backed up by Time Machine.
On December 23rd, in another thread, Kimo said (see also Peggy Lynn's posts, above):
"At this link you'll find the Fusion 1.1 release notes http://www.vmware.com/support/fusion/doc/releasenotes_fusion.html
"Fusion 1.1 was the upgrade that Vmware provided at the end of november.
As you can see they don't mention any issue with Time Machine.
But searching around I've found the Fusion 1.1. RC1 release notes at this link
http://www.vmware.com/beta/fusion/releasenotes_fusion.html
"In this document you can find this section:
"-Leopard's Time Machine feature causes VMware Fusion 1.1 RC1 to hang.
In Mac OS X 10.5 (Leopard), the Time Machine feature interferes with the Virtual Machines directory, causing VMware Fusion to hang when you launch it.
Workaround: Configure Time Machine to exclude the Virtual Machines folder.
This problem is planned to be fixed for the upcoming VMware Fusion 1.1 GA release. Virtual machines will be excluded from Time Machine backups...
"...and they did it!
"They should announce it, in the right way, with the final 1.1. release notes. I can confirm, now, that my first 2 backups (of my vmware files) were done before the fusion 1.1 upgrade.
The day I've installed the upgrade backups have been stopped.
"I'm not glad for this, It should be a decision of mine..."
I completely agree with Kimo. I have reviewed the 1.1 GA release notes, again, and can find no mention of Time Machine. Someone new to Fusion who trialed or purchased Fusion 1.1 GA would not be able to tell from a read of the Release Notes that her/his VM was excluded from TM backup. VMware indicated to me that they made this move, in cooperation with Apple, because the problem outlined above would occur if TM ran when a Fusion VM was active.
I have been waiting for Dave Nanian to e-v-e-n-t-u-a-l-l-y update SuperDuper! to an exalted state of Leopard compatibility and, frankly, have in the interim been doing less frequent clone backups with CCC. As a consequence, I have been less protected (with respect to my data in the Vista VM) than I thought I was.
Let me state the obvious: because, for many of us, the data in our VMs is precious, it is irresponsible for VMware to make a unilateral and fundamental change in a backup modality that is, after all, part of OSX, without giving the user a choice (the bug doesn't manifest itself if the VM isn't active; I just shut mine down to do periodic TM backups without mishap) and (ii) proactive notification of registered users -- they have the email addresses! That Apple was apparently a part of this is quite disappointing as well.
More of the obvious: if you are a Fusion user, you should -- for sure -- rely on a backup approach other than TM to protect your VM data.
Regards.

Time machine Backup of bootcamp, Virtual Machine, and VM based on Bootcamp

I have read posts that contradict each other, so...
Does Time Machine backup Bootcamp? I think the answer is no.
Does time machine backup a Parallels Virtual Machine (bootcamp or other) as expected? I believe the answer is no, any changes to the VM will cause the entire VM to be backed up. So, I think you should do an occasional back up in time machine that includes all VMs, then set in VMs to not be backed up by time machine...right?
Are there any considerations of a Parallels VM for boot camp? For example, does it mater if you do windows update from the VM or the bootcamp? I think the answer is no, you can do anything from either and get the same results.
thanks
bob
