[Users] Backup virtual machines on ovirt
by Daniel Rodriguez 17 Feb '12

17 Feb '12

Hello, we are testing ovirt and RHEV in order to install both in our company instead of Vmware Vsphere. One thing we have seen, googling on Internet, there is nothing about backup virtual machines. I have seen Acronis as a backup solution but I found it too expensive for us at this moment. I'm thinking more something like ghettoVCB.sh <http://communities.vmware.com/docs/DOC-8760>on Vmware, a script that can connect to VCenter / Esx(i) and it's free of cost or a product with a not very expensive license. Thank you very much. Dani R.

The machine I'm testing on when you goto the boot menu will show UEFI: $CD_DEVICE_NAME or for boot entries for ovirt it would show: oVirt Node Hypervisor If your grub cd supports efi booting it will be noticeable in the boot menu. In order to do an efi installation it has to be booted in efi mode for it to properly setup the boot entries.

[Users] Still unable to boot in system with UEFI
by Federico Alberto Sayd 15 Feb '12

15 Feb '12

Hello: Recently I downloaded the ovirt stable node image. According to releases notes since 2.2.2 UEFI installation bug has been fixed, but I still can't boot from my server with UEFI. Ovirt installs without problem, but when the system reboots nothing happens, the system don't boot. Then I try to boot with super grub disk 2 live cd, it detects ovirt installation and boots the system. I think that still there is a problem with UEFI in certain hardware: Mi system is a IBM blade center HS22 7870 Can anyone confirm problems with UEFI in 2.2.2 version? Thanks Federico

Re: [Users] Possible to migrate from an existing KVM/Libvirt VM (installed in an LVM) ?
by Richard W.M. Jones 14 Feb '12

From: Morgan Cox <morgancoxuk(a)gmail.com> > Can an existing KVM/Libvirt VM (installed in an LVM) ever be migrated to > an Ovirt node (offline migration is ok.) ? [Sorry this isn't threaded -- I wasn't subscribed to the list until now] The answer is that virt-v2v ought to work with oVirt. It was developed originally against RHEV-M 2.2 and, later, 3.0. Of course KVM guest images should require only minimal changes, since they should already support virtio etc., certainly for Linux guests. So in many cases virt-v2v would be a no-op, and simply copying the disk image may work. Matt ...?

Re: [Users] Pxeboot - pwd/login issue
by Li, David 13 Feb '12

13 Feb '12

Hi Mike, I ran into the login/pwd problem again with this new build. Kernel option adminpw worked but only for a short time. I was asked to change pwd immediately after login but then rejected again after I did that. There was an short-lived error message on the screen but I wasn't able to capture it. I tried the latest from archipel source and it worked without password issue. I pulled it from: git clone https://github.com/primalmotion/Archipel.git There might be a few updates right after you pulled it last time. Would you mind merge the new updates into ovirt node again? Thanks.

[Users] Difference between RHEV and ovirt
by patrick 13 Feb '12

13 Feb '12

Hello all, In our company we want to use either RHEV or oVirt in a production environment. After testing RHEV for 30 days we are happy with the stability and features. Can someone explain the difference between RHEV and oVirt? Are there maybe some features just available in RHEV like Windows guest drivers or someting like that? I'm not sure if I get this right, but as oVirt is the upstream of RHEV does this means that new features like hot add nic etc. are first available in oVirt and afterwards in RHEV. Does oVirt has any drawbacks compared to RHEV other than support? Thanks in advance Patrick van der Wiel
