OVM Server Got Rebooted

hi,
i have ovm 2.2 setup
i checked log i.e /var/log/messages
i saw it was trying to connect 10.180.8.119 as a cluster node but it is actually a VM Guest.
i can't understand why it is trying this
please suggest
below is the log from /var/log/messages

The connection is created by the machine with ip address 10.180.8.119, so check that machine, to see why it is trying to create a connection to this machine at port 7777. Does it have ocfs2 installed? If so, check its /etc/ocfs2/cluster.conf to make sure it is correct.
Actually, it looks like that machine is sending 0x47455420, which is "GET ". Could be a web browser pointing at the wrong machine, or some other tool trying to connect via HTTP.

Windows Server 2012 reboots while removing the Hyper-V vSwitch.

I have a WIn2k12 server with Hyper-V running. While removing the vSwitch configured in Hyper-V, the server got rebooted. In the event logs below mentioned error was notices.
he computer has rebooted from a bugcheck. The bugcheck was: 0x00000019 (0x0000000000000024, 0x00000000000000f2, 0x0000000000000001, 0xfffffa800b9ba6c0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 072314-20248-01.
The Windows has generated a MEMORY.dump which is ~570MB in size. Is it possible to analyze the MEMORY.dump and find the cause for a server reboot.
Can you please someone help me to narrow down the root cause of this issue and how to avoid this issue in the future.

Hi,
Thanks for your reply. I analyses the the MEMORY.DMP using the WinDbg. Provided the debug output below. Will this help you to narrow down the root cause and let me know if any similar issue faced by someone else.

Windows 2008r2 server got abruptly rebooted with Bugcheck error.

Today our 2008r2 server got abruptly rebooted, what we found out in event viewer was something like this "The computer has rebooted from a bugcheck". The bugcheck was: 0x0000001a (0x000xxxxxxxxx). Also a .dmp was created which i got analyzed,

I would recommend that you start with checking that your RAM is okay using memtest86+. If an error was reported then I would recommend replacing the faulty RAM.
If this does not help then please try to temporary disable the security software running on your server and check again.

OVM Server 3.2.1 install reboots server

I have been trying to install OVM Server on an IBM xSeries 336 server. OVM Server 2.2.1 was previously installed on this server.
Trying to install 3.2.1 now and I get to the splash screen booting from the CD. I press [Enter] to begin the installation. Once the process reaches the point of 'Loading SCSI driver', the server reboots. I have tested the media on other machines without issue. I have also tested the server with OVM Server 2.2.1 media and the install progresses normally to the end.
I suspect there are missing drivers causing the install to fail. Is there a way to load the missing drivers during the install process?
Thanks in advance,
UPDATE: I have successfully installed OVM Server 3.0.2... Not exactly what I wanted but....
Edited by: SBaugher on Feb 20, 2013 11:04 AM

Oracle VM 3 is entirely different from 2.2.1.
take a look at the release notes for 3.2.1 There are few instances in which you have to specify different boot parameters for the installation to work.
http://docs.oracle.com/cd/E35328_01/E35329/E35329.pdf
You might have a MEGARAID product.
If you are installing Oracle VM Server on a Sun Fire X4800, you must provide extra parameters when
booting from the installation media (CDROM or ISO file), or when using a kickstart installation. These
parameters allow the megaraid_sas driver to load correctly.
If booting from the installation media, press F2 when the initial boot screen is displayed and provide the
following additional parameters as part of the boot command:
mboot.c32 xen.gz extra_guest_irqs=64,2048 nr_irqs=2048 --- vmlinuz --- initrd.img
If using a kickstart installation, add the additional kernel parameters to the PXE configuration file.

OVM server Reboot

Dear Gurus,
I would like to get clear some of my doubts regarding Oracle VM server.
Actually i am very new to OVM and we are having a OVM setup and the ovm version is 3.2. We are having a server pool having two servers.
Doubts :
1. During the creation of server pool it was asking us to point to a repository, however after shown of Repository i unable to seem them for further use and i had to create another Repository in order to host the iso, templates and VM disks ets. Where does it gone or does it used for pool hearbeat ?
2. Can't we use the the ISO's already exported from other NFS servers so that we can simply mount the iso for installation of VMs like in VMWARE.
3. after creation of server pool we had created couple of Test VM and were trying to reboot the OVM server so that the VM can move across the physical boxes for fail over. However during the OVM server reboot my VM actually reboots instead of Live migration. According to Oracle documentation they say either i have to put the OVM server in Maintenance Mode or i need to move the VMs manually. also it says the vms either will reboot or migrate online. in my case VMs are getting reboot and moves to other available server.
Please clear my doubts so that i can learn further about OVM and able to explain it to customer.
Thanks.

Cluster Not Available error when booting OVM server DOM0 from USB

Hi all,
I have been wanting to run OVM 2.2 from a USB stick for a while now. I ran through the install CD today and saw there was a 'minimal USB install' option on the installation screen. So I plugged in a 4GB USB stick, rebooted, and ran the USB install.
After a while, the install completed, OVM booted up perfectly it seemed, and I was happy.
The server had no local storage apart from this USB stick as we are going to be hooking it up to an iSCSI target for guest VM storage.
This was a new lab setup, so I got the VM Manager running on another system, connected to the USB booted OVM server, and went to create a pool.
Running the 'test connection' that worked fine.
Trying to add the pool - failed. I got the error 'Cluster Not Available'
On the OVM server I did a repos.py -l and nothing gets listed.
I understand that for HA you need a repository with shared storage. However, before I have used these same install CDs with a singe local hard disk, to get OVM server running, and it did so fine.
So what's different with the USB disk install that means you don't get a repository?
Do I have to create a special repository LUN, manually connect the OVM server to this, and then use repos.py to create it?
Cheers,
Jeff

Ok I have read, re-read related parts of the underground manual and have hit a brick wall with the 'simple' task of setting up a NIC for dedicated iSCSI traffic. The manual does not cover this task in the iSCSI SAN section.
So I'm in a catch 22.
My OVM server boots up, with it's single management NIC configured, but once booted - I don't want to connect to the iSCSI target via this network - I need it completely closed off.
I want to use another NIC (or bond of two) for dedicated iSCSI traffic to and from the OVM Server.
However, the underground manual strangely only seems to cover a single NIC configuration! It looks like he assumes you are going to be running iSCSI on your management NIC, which I can only think is incredibly bad practice.
I have installed OVM with the linux asknetwork - this did not give me the option to configure additional interfaces.
I then manually edited /etc/sysconfig/network-scripts/ifcfg-eth1 on the OVMServer, restarted network, restarted the entire box - I can ping my new NIC / IP locally from within the OVM server, but I can not connect to the iSCSI target, nor can I ping the iSCSI NIC on the OVM server from the target.
This is such a simple thing to try to achieve - super frustrating...

Failed OVM Server Upgrade from 3.0.2 to 3.1.1

I was trying to upgrade my OVM Server environment from *3.0.2* to *3.1.1* using the CD. I got the following error message after choosing the Upgrade option: Oracle VM server 3.0.2 (cciss/c0d0p2). The other option was to Reinstall System.
+"Error mounting device sda2 as /:+
+Device or resource busy+
+This most likely means this+
+partition hast not been formatted.+
+Press OK to reboot your system."+
My hardware is a HP BL465c G7 server, which is certified by Oracle to run the OVM 3.1.
http://linux.oracle.com/pls/apex/f?p=117:2:3396212307219555::NO::P2_CERT_ID:1871
Any advice that can help me find the way to upgrade my servers?
Thanks in advance,
Andrés L.

Hi,
I tried "yum update -y" and after reboot I encountered a kernel panic after the following message: switchroot: mount failed: No such file or directory.
So I got to reinstall ovm 3.0.3 from scratch.
Maybe the hard disk drivers in 3.1.1 kernel version (uek2) are not compatible with my server disks.
If someone has an accurate explanation to this issue, could be helpfull.
Best Regards,
Andres Loaiza.

Lost connection between ovm-manager and ovm-server (ovm 3.1)

Hi,
I have a manager as a VM on my laptop and a physical server as an ovm-server. Everything is fine when i boot the server but after some time, the manager stop to show the information from the server. in the ovs-agent log file the following messages are repeated regulary
[2013-08-29 13:06:19 6160] DEBUG (notification:289) Trying to connect to manager.
[2013-08-29 13:06:20 6160] DEBUG (notification:291) Connected to manager.
[2013-08-29 13:06:20 6160] ERROR (notification:316) No manager Core API server object for 10:60:4b:88:bc:24:10:60:4b:88:bc:25:fe:ff:ff:ff.
[2013-08-29 13:06:34 6171] ERROR (notification:64) Unable to send notification: (111, 'Connection refused')
I did not reboot neither the server nor the manager. No IP change. Rebooting the manager has no effect.
The only way to restore communication is to restart the ovs-agent on the server, but this restart disable the network card. I must be physical on the server to restart the network.
any help will be very helpful
best regards
Jean-Marc

Hi,
The are many steps to verify:
Verify with your firewall on the Oracle VM Manager system (service iptables stop).
Verify with a ping between OVM Manager and OVM Server using the IP Address and using the hostname for each one (from OVM Manager : ping ovm-server ; and from OVM Server: ping ovm-manager).
I hope this can help you
Best Regards

How to configure local disk on OVM Server as storage space to create VMs

Hello,
We have installed OVM Server 3.1.1 on a machine that has 250 GB of Hard disk space [Single disk].
While installing used an option - Remove all partitions and create a new default partition layout.
Around 4GB has been used and remaining 246 GB is left as free space.
From OVM Manager - the server is discovered but didn't discovered the physical disk [i.e. remaining 246 GB raw disk space].
Can someone help me to understand how to use local disk as storage space for creating and running VM's.
Thanks
Srinivas

You can? You've used every conceivable BIOS out there? You must really be full of yourself. There is absolutely no BIOS that I know of that gives this basic function. BIOSs do not "hard partition" anything. A "BIOS" is not made for such things. Do you even know what "BIOS" stands for?
I wonder why there is some many wanting to do this and are having problems.... I mean if it is such a straight forward thing to do..... It must be down right "intuitive".
You maybe speaking of a RAID "BIOS" but you obviously think you're not. Some motherboards have integrated RAID abilities. Intel RST comes to mind... BUT this isn't a feature of a MOTHERBOARD BIOS.
I've got some $50,000 servers that will not break a single hard drive up into multiple logical drives..... Now, I haven't worked on a "Stinkpad" for many years. Don't want to. However, I have never seen one that would do what you're saying you're doing.
You maybe trying to help.... but you're leading people down a wrong path.
Its just as easy to run virtual box and use the virtual box templates for Oracle VM. In fact, its more practical if you want to run Oracle VM on a laptop for testing purposes than blowing everything away and attempting to setup different LUNS on a single hard drive.
For your review...
http://www.oracle.com/technetwork/articles/servers-storage-admin/configure-vm-templates-1656261.html
Although it's more reliable to use a separate location (such as an NFS share) for a storage repository, you can use a local disk of your Oracle VM Server instead, thus taking advantage of the local storage option. Beware, though: Oracle VM Server 3.0 doesn't allow you to utilize the unused space on the physical disk it's installed on. For local storage, you'll need at least one more physical disk. In other words, you'll need a total of two disks at minimum on your Oracle VM Server host if you want to use local storage. In practice, though, local storage is not a primary use case. The major downside to this approach is that local storage, by definition, cannot be shared between different servers.

Oracle VM 3.1 Server automatically reboots after - stopping it

When I try to stop my OVM 3.1 server, using shutdown, or init 0 the server stops, but automatically boots again....
Anyone run into the same problem?
Thanks for all your suggestions

The OVM server? Yes OVM Server :)
I've not seen this before. It could be that the hardware doesn't support the poweroff signal from the OS. Although I'm not sure if it is that much of an issue, as you rarely turn off / on the OVM servers themselves. You can easily power it off if it does a reset not a poweroff.The reboots after "init 0" disappeared once after I added a third NIC to my box, and dedicated it for virtual machines
ie, my Windows 7 box, on which I setup the entire VM infrastructure using VirtualBox has 3 NICs. Two for the VM Server, and the third one for the VM Manager.
The second NIC with VM Server configured to handle the traffic from Virtual Machines, isolating the 1st NIC for all other VM Server traffic. No more rebooting with VM Server and always shuts down with a "init 0"
Hope this info is useful for few others out there

raj
Adding something I missed with last post
Following sequence is always used to shutdown the VM Server as my setup has NFS shares setup from VM Manager server itself
1. Shutdown VM Server first (Stops all heartbeats etc gracefully)
2. Stop OVMM service on VM Manager server
3. Shutdown VM Manager Server

H/W of Win7-- VirtBox-- OVM Serv -- EBS/lin64bit

What is the best practice to follow if I have to install Virtualbox, OVM Serv, Linux, EBS, Weblogic,SOA, GRCC, GRCM etc. Should I create a separate partition for each and of what sizes ?
I got a desktop 8GB/1TB and laptop 4GB/500 GB + external 500GB. What should I install where for better performance. How much RAM should I allocate to Virtbox, OVM serv etc.

For the size, it depends on what you are installing -- See the hardware requirements in the installation manual for each product for details.

OVM Manager install for running OVM server for SPARC plateform

Guys,
I have to install and deploy OVM Manager for managing an existing OVM server for SPARC.
When try to run ovs-agent-setup command, it fails telling that ovm server has not good configuration and exits!!
ovs-agent ** ERROR: The vds service is not configured on the primary domain
Trying to fix by resetting factory default configuration, then poweroff domain and poweron aain but nothing!! I got same error and ovs-agent service is in maintenance.
Now we have create ldoms and servers are in production!! We cannot reset configuration now.
Is-it possible to deploy OVM manager, fix ovs-agent issue without impacting actual vm??? How to do this? I assume that vm created with ldm commande can not be provision with ovm manager.
Please help!!

Hi,
Windows Server 2008 R2 supports two mutually exclusive methods for setting quotas on the amount of file system resources a user can use—disk quotas or directory quotas. Disk quotas are applied to specific users and limit the amount of disk space that user can
use on a particular volume. Directory quotas are applied to all users and limit the amount of disk space that users can use in a particular folder and its subfolders.
I do a test on my pc and find there is no priority between the two quotas, it depends on which quota is smaller. So user A can only save 1 GB files in the folder.

Mandy

OVM Server in failed status after a power outage

Hi,
We recently experienced a power outage and the OVM environment completly reboot.
The OVM manager come back as well as the ovm server.
The issue is i can't anymore control the OVM servers from the manager as the both servers are in a failed status with the following message:
Job failed commit (internal) due to If the IP address of this server has changed, please delete the server: oracle55, and re-discover.
Tue Nov 06 16:32:38 CET 2012
com.oracle.ovm.mgr.api.exception.IllegalOperationException: If the IP address of this server has changed, please delete the server: oracle55, and re-discover.
Interesting enough, I can manually restart the VMs (xm create...). Thus I'm not really in favor of deleting and rediscovering the servers.
Obviously the ip configuration didn't change (no DNS).
Any idea how to fix this?
Thanks for your help.
Yann

Hello!!
Maybe it could be ovs-agent service from the server not communicating correctly with VM Manager??
You should login to server and see what command "service ovs-agent status" returns!!
If everything is running maybe a "service ovs-agent restart" could resolve something...
Also check that there aren't locked processes...under "/var/run/ovs-agent/" check that there is NOT any ".lock" file.
Greets!! ;)

Mac OS 8.6 Auto network connect to a server after reboot is not working

We have multiple old blue and white systems on a network. All but one will automatically connect to the network when rebooted. I have gone into Chooser, Appletalk, put in the server IP address, put in the server password, checked the boxes that say remember Server name and password for next startup. I can connect at that time with no problem. When I reboot, the server does not automatically hook up. I have to go back into Chooser, etc. I created an alias on the desktop, but it still prompts me for a password to connect. I have performed a clean install of the Mac OS 8.6. It still does not connect to the server after reboot (after configuring all the settings again after the clean install). Please help..
