[ovirt-users] Re: Weird problem starting VMs in oVirt-4.4

Yes, so the bug has been fixed upstream and the backports to release-7 and release-8 of gluster pending merge. The fix should be available in the next .x release of gluster-7 and 8. Until then like Nir suggested, please turn off performance.stat-prefetch on your volumes. -Krutika On Wed, Jun 17, 2020 at 5:59 AM Nir Soffer <nsoffer(a)redhat.com&gt; wrote: > On Mon, Jun 8, 2020 at 3:10 PM Joop <jvdwege(a)xs4all.nl&gt; wrote: >> >> On 3-6-2020 14:58, Joop wrote: >>> Hi All, >>> >>> Just had a rather new experience in that starting a VM worked but the >>> kernel entered grub2 rescue console due to the fact that something was >>> wrong with its virtio-scsi disk. >>> The message is Booting from Hard Disk .... >>> error: ../../grub-core/kern/dl.c:266:invalid arch-independent ELF maginc. >>> entering rescue mode... >>> >>> Doing a CTRL-ALT-Del through the spice console let the VM boot >>> correctly.
