[ovirt-users] Re: [ovirt-announce] Re: oVirt 4.4.8 Async update #4
Hi Diggy, If you have updated to oVirt 4.4.8 prior to 4.4.8.6 async release, it means your system got impacted. To fix it, you need to set some value to HEVM timezone and then try again (at least how I understand it). Regards, Marina.

[ovirt-users] Re: about the Live Storage Migration
Sadly, libgfapi has some limits and some of them are like your case. If it's a linux VM, you can create new disk from the Gluster Storage and then attach and clone/pvmove it from within the guest. Another approach is to disable libgfapi, shutdown the vm, power on the VM, migrate the disk and later again enable libgfapi and restart the VM (power off and power on cycle).

Гринуич+3, Tommy Sway написа: From the document: Overview of Live Storage Migration Virtual disks can be migrated from one storage domain to another while the virtual machine to which they are attached is running. This is referred to as live storage migration. When a disk attached to a running virtual machine is migrated, a snapshot of that disk’s image chain is created in the source storage domain, and the entire image chain is replicated in the destination storage domain. As such, ensure that you have sufficient storage space in both the source storage domain and the destination storage domain to host both the disk image chain and the snapshot. A new snapshot is created on each live storage migration attempt, even when the migration fails. Consider the following when using live storage migration: You can live migrate multiple disks at one time. Multiple disks for the same virtual machine can reside across more than one storage domain, but the image chain for each disk must reside on a single storage domain. You can live migrate disks between any two storage domains in the same data center. You cannot live migrate direct LUN hard disk images or disks marked as shareable. But where do users perform online storage migrations? There seems to be no interface. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/GRFF5WF7TEWL3P66LA24C5NJWDAR5JUP/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PZWERFCWQBTSWP3NN2D2TPLMJARQWAAW/

Based on the engine log, there should be also some CopyImageError in the vdsm log - this would give us more context where exactly it failed. Also, given that libvirt block job failed, is there any error in libvirt/qemu log? > > > > > > > > > -Original Message- > From: users-boun...@ovirt.org On Behalf Of Vojtech > Juranek > Sent: Monday, September 27, 2021 3:23 PM > To: users@ovirt.org; Tommy Sway > Subject: [ovirt-users] Re: about the Live Storage Migration > > On Sunday, 26 September 2021 14:07:01 CEST Tommy Sway wrote: > > Why always fail ? > > please provide relevant part of engine and vdsm logs signature.asc Description: This is a digitally signed message part. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/WTFNVBLJIHK4W2CZINDXP4ON56JAQIZY/
[ovirt-users] Hypervisor broken
Hi all, I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running. As said... till now... I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base. Yesterday I had a power outage which left the system unbootable with the following errors: error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number. error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first. Press any key to continue Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore. https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-res... does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system. When booting the ovirt kernel, I get a rescue prompt with the following error: "Warning: /dev/onn/ovirt-node-ng-4.4.6.3-0.20210518.0+1 does not exist" Is there a way i can start the installer in troubleshooting mode so I can do a reinstall and keep the current configuration or can I just reinstall and import the current datacenter in it? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/U7REUWJN7KXNURAQGTBXL4VKOXZZI4YG/
