OVM 3.1.1 DR Configuration

Hi.
We have a business requirement to configure a DR site for our OVM 3.1.1 environment. Any of you dabbled with DR for OVM, if so how and what do we need to do to replicate the VM's from our production site to the DR site?
Maybe I should have ask this fist, it is possible to have a DR site for OVM 3.1.1?
Thanks.

Greetings,
I have had the opportunity to design, deploy and support dozens of Oracle VM DR solutions. Please consult my on-line book named the Oracle Cloud Cookbook, specifically the Oracle Cloud Reference Design chapter section "Oracle VM for x86 Disaster Recovery". I will post the link, although the forum moditator will most likly clip it :-)

How to configure multiple IP-Adresses on one NIC in OVM

Hi guys,
we have some OVM Servers 2.2.1 installed. They all have three NICs in them (eth0-2). For eth0 and eth2 we need multiple IP-Adresses configured to work with our storage solution. The configuration should look like this:
eth0:0 - 192.168.31.x
eth0:1 - 192.168.33.x
eth1 - 192.168.0.x
eth2:0 - 192.168.32.x
eth2:1 - 192.168.34.x
I tried creating gonfig files ifcfg-eth0:0 in /etc/sysconfig/network-scripts with the following content
DEVICE=eth0:0
BOOTPROTO=static
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.31.3
TYPE=Ethernet
HWADDR=00:1b:21:06:f0:fa
But it does not work. Neither eth0:0 nore an additional xenbr is configured when i restart.
I can configure multiple ip addresses for xenbr0 by calling something like "ifconfig xenbr0 192.168.31.x". But these settings get lost as sonn as i reboot the server.
I have already searched google, forums and blogs for a solution but could not find one. I thought that this should be a pretty common task. In "normal" linux it is not an issue at all.
Has somebody any experience with a setup like this? I would really apreciate your help.
Thanks

Hi,
configuring IP aliasses seems to work the same way like configuring VLANs. You will have to configure the appropriate bridges at system startup manually.
E.g. this little script is what I use to configure VLANs and briges on my OVM:
#!/bin/bash
echo "Configuring VLANs and bridges\n"
echo "Configuring VLAN 24 on eth2"
vconfig add eth2 24
brctl addbr br2.24
brctl addif br2.24 eth2.24
ifconfig eth2.24 up
ifconfig br2.24 up
echo "Configuring VLAN 31 on eth2"
vconfig add eth2 31
brctl addbr br2.31
brctl addif br2.31 eth2.31
ifconfig eth2.31 up
ifconfig br2.31 up
This script is run at startup by init using this startup skript in /etc/init.d, which is what I think you're missing as you can already seem to bring up the needed IPs manually - you'd have to change the chkconfig accordingly, that is make sure that the config script gets startet after the network has been brought up, like this: # chkconfig: 2345 11 91
[root@oraclevm01 ~]# cat /etc/init.d/vlan-config
#! /bin/bash
# vlan-config configure VLANs
# chkconfig: 2345 11 89
# description: Configures VLANs at boot time before the \
# network is started.
### BEGIN INIT INFO
# Provides: $vlan
### END INIT INFO
# Source function library.
. /etc/init.d/functions
if [ ! -f /etc/vlan-config ]; then
exit 0
fi
# See how we were called.
case $1 in
     start)
               # configure vlans
               /etc/vlan-config
          echo $"Usage: $0 {start}"
          exit 1
esac
exit 0

Question on adding new server to existing pool in OVM 2.2 environment

I have an existing iscsi based server pool with one server attached to the pool. I am adding a second ovm server. I have configured the iscsi and multipath modules and can see the repository lun.
I then added the server to the pool via ovm manager, but the server is not fully participating as the agent did not create a mount point for /OVS so I can't see the repos directiories from the new server. A "df" does not show the device as it does on the first server.
The manager gui does show the server as part of the pool even though we received an error.
In the ovm manager log, we see the following messages.
Check prerequisites to add server (ovm2.highlinehosting.com) to server pool (san_pool1) succeed
During adding servers ([ovm2.domain.com]) to server pool (san_pool1), Cluster setup failed: (OVM-1011 OVM Manager communication with ovm1.domain.com for operation HA Setup for Oracle VM Agent 2.2.0 failed: errcode=00000, errmsg=Unexpected error: <Exception: ha_check_cpu_compatibility failed:<Exception: CPU not compatible! {'ovm1.domain.com': 'vendor_id=GenuineIntel;cpu_family=6;model=44', 'ovm2.highlinehosting.com': 'vendor_id=GenuineIntel;cpu_family=6;model=46'}> )
I'm not sure why it's complaining about cpu compatibility as we are not using any HA features at this time, and both servers are identical in make and model. They are both equipped with the same cpu type and speed.
I checked ocfs2 network connectivity by executing the command "nc -zv nodename 7777", which ran successfully from both nodes. The manager was able to propagate a valid cluster.conf file to both servers. I restarted the ovs-agent service on the new server.
Are there any other configuration steps that I need to take on the new server before trying to add it to the pool? I do need to tread carefully as I have live guests running in the pool.
Thx

If I have to go the route of using a separate pool for each server, do you have any suggestions on how I would be able to access the repos of server1 from server2 if server1 were to go down hard? I don't mean to access it as a repos for running the vms, but just to be able to copy the vm files over to the running server.This would be possible if you were using NFS for your storage, but not if you're using FC or iSCSI, as the LUN is formatted with the OCFS2 cluster ID of each pool, so probably wouldn't be able to be mounted by another pool. Your best bet is to upgrade to Oracle VM 3.0 so that you can create a pool that contains both servers: you won't have live migration, but HA will still work just fine.

I will mention that I had the following happen:
I tried to do a demo install.
It failed because I didn't have /etc/hosts setup properly.
I fixed that problem, and restarted the installation.
The second time, I got an error similar to the one you go.
It turned out that the first installation attempt got XE half-installed, but not operational.
I fixed it all by carefully shutting down the half-running database, and removing XE (with RPM), clearing out /u01, and retrying it.
That may all be totally irrelevant to what you're seeing, though.

OL5.8 OVM Guest number of CPU´s

Hi,
does anyone can help we understand if it is possible and a good idea to configure more virtual CPU´s
in a OVM Guest as cores integrated in the physical hardware.
We have a 2 cpu 6 core OVM hardware and try to configure 20 virtual cpu´s in ONE guest system.
I don´t like that idea....

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

Has anyone seen this problem before?
Thanks, Franco.

Well, in the end we had a problem we the NFS share, it was possible to mount it on other servers but all read operation failed, we moved the iso to a different nfs server and it worked just fine. Closing the thread.

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.

Configure iSCSI multipath in OVM 3.1.1 with storage plug-in not possible ?

I have a configuration with 4 iSCSI paths to storage system. All is working fine if the discover and login
process was performed manual. Multipath is working well with 4 paths.

I want to configure iSCSI multipath in OVM manager using specific storage plug-in.
I proceed “Discover SAN Server” with following parameter:
Name: Storage-Name
Storage Type: iSCSI Storage Server
Storage Plug-in: Fujitsu ETERNUS
Admin Host: IP-Addr. of storage system
Admin Username: user name to access storage system
Admin Password: password
Access Host (IP) Address: 192.168.10.1
After this configuration I see my storage system and assigned physical volumes to an access group.
Now the volumes are available on the OVM storage server, >>>> but I lost the multipath functionality <<<<<.
# multipath -ll
3600000e00d1000000010000000120000 dm-1 FUJITSU,ETERNUS_DX400

`-+- policy='round-robin 0' prio=50 status=active
`- 33:0:0:1 sdd 8:48 active ready running
The reason for this behavior is that only one Access Host (IP) Address can be specified.
With this IP address a session was established … but only 1 session and not 4 !!
How can I specify the remaining 3 paths to have proper multipath functionality?
I know that Citrix XenServer accepts more Access Host (IP) Addresses,
e.g. 192.168.10.1,192.168.10.2,192.168.20.1,192.168.20.2
Thanks for help.

@user12273962
Yes, you are right. The storage plug-in is for management of the storage within OVM.
This is working well, but I'm still missing the multipath fuctionality. This storage plug-in is not responisble
for establish the multipath, but OVM should take care of this.
@budachst
Yes, OVM did only open one session and loggin only to one target, because only one Access Host (IP) Address: 192.168.10.1
can be specified.
# iscsiadm -m session
tcp: [21] 192.168.10.1:3260,25 iqn.2000-09.com.fujitsu:storage-system.eternus-dx400:CM0CA3P0
In my point of view it is not possible to configure the remaining targets, so this is a design problem.
Any new inputs and informations are welcome.

Please help about OVM network configuration

I have ready RAC OVM templates and below is the instructions.
Can someone explain this to me?
I want to create a OVM server and OVM manager on virtualbox. But I couldnt und network configurations.
Following are the non-standard requirements for your OVM setup:
The VMs must be able to interact with the OVM server (Dom0) at IP address 192.0.2.1
The OPVM server (Dom0) must supply NTP and DNS services to the DB VMs
The OVM server must be configured with 3 virtual bridges (virbr0, virbr1, virbr2) to support the different Database Machine networks.
Here are some notes, assumptions and requirements associated with these VMs:
1. The public network interfaces on all the VMs occupy addresses in the 192.0.2.X range. The private storage network and cluster interconnect on all the VMs occupy addresses in the 192.168.1.X range.
2. All the VMs assume access to NTP and DNS services provided by servers at 192.0.2.1. One way to provide these services is to configure a bridged network interface on 192.0.2.1 under Dom0 and to configure NTP and DNS services on Dom0. Another way is to create an additional VM with a primary network interface on 192.0.2.1 which offers the required services.

Then I will import some OVM templates to that system.
No - not possible using Virtualbox - as noted, OVM and Virtualbox are different technologies and an OVM install will destroy the native OS.
I believe you are confusing technologies and terms. If I understand your needs, you are wanting to install Virtualbox on your OS, then create VMs using Virtualbox and/or import Virtualbox VM templates. Note that Virtualbox VM templates are different than OVM VM templates - the latter can only be installed on OVM Server.

Not able to configure yum update or yum repository on the OVM 3.1.1

I just downloaded the new OVM 3.1.1 but I am having a tough time to configure yum update.
There are no repositories present in the yum.repos.d.
How should I download the repositories so that my remaining packages get installed automatically.

Hi,
please check the /etc/yum.repos.d
[root@ yum.repos.d]# pwd
/etc/yum.repos.d
[[email protected]]# more public-yum-ol6.repo
and take a look to the public-yum-ol6.repo for
[ol6_UEK_base]
name=Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch)

You should set "enabled=1"

OVM 3 Generic Storage Plugin. Acess Group configuration causes server crash

Our iSCSI management is currently entirely done manually at the servers console, because we still don't have a SAN Equallogic storage plugin.
At OVM Manager interface, what we thought being just useless in our case (SAN Access Group), is the actual iSCSI connection (and disconnection..) management for servers.
Following the upgrade to 3.2.1, setting up the SAN did nothing more than what we do manually. But undoing part of it caused the crash.
All over OVM Manager, any operation/setup that could impact running VMs is denied... Except there, at the real root of everything.
Removing a iSCSI initiator from that panel disconnects abruptly the iSCSI disk, !!!! without warning !!!!.
Then, after the 60s timetout, the physical server reboots.
It is still not clear if we get a benefice to setup that "Access Group" of the SAN or not. At least, once setup, we know that we'd better keep it...

OVM 3.1.1 how to refresh missing network configuration

hi,
OVM Server hardware:HP BL490c blades.
o/s: OEL5.6
OVM version: 3.1.1
chain of events:-
1)virtual connect issue led to temporary loss of some networking, now restored
2)interrogating OEL5.6 shows all networking present
3) interrogating OVM console shows missing network config in Servers & VMs, on ethernet ports drop down.
Q: how can i refresh/re-add the missing ethernet ports & bonds back into OVM?

I think you're confused. Isn't your OEL a VM guest? Virtual nics are different from actual physical nics you see at the VM Server level.

How many time to install/configure OVM Manager and OVM Server ?

Hello,
I wish to have your experience feedback on the mean time needed to install both OVM Server and OVM Manager in a production environement, with e.g : 2 CPUs, 4 G of RAM, or for 4 CPUs and 8 G of RAM.
Regards,
Lionel

Not enough information. XE is not supported in a production environment so you will need to install a SE or EE version of Oracle Database. I would personally use EE because the Virtual Manager comes with a single use license that covers running the VM Manager on either edition. No extra cost to run EE over SE.
You can use kicstart to rapidly deploy any VM Server. If you get your scripting right... it takes less than 10 minutes.
