Hi,
we have the same issue since oVirt 4.0.
Because we need always several disks, we have the boot disk as virtio and all others as
virtio-scsi.
With this approach, boot disk is always vda and all other disks are then sda, sdb and so
on. They change nearly every time, we reboot.
In Linux, you can mount also disks not only by /dev/sdX, you can also mount them via UUID
of the disk or by label, ... With this, the disks can always be correctly identified and
mounted.
Here an example:
LABEL=cloudimg-rootfs / ext4 defaults 0 0
/dev/disk/by-label/log /var/log auto defaults,comment=cloudconfig 0 0
/dev/disk/by-label/tmp /tmp ext4 defaults 0 0

Betreff: [ovirt-users] After adding a disk via GUI the VM does not start anymore
Hi,
when I add a disk to a debian 9 VM the VM cannot boot anymore. The VM is stating that
/dev/sda1 cannot be found anymore. When I remove the added disk everything works as
before.
Could someone please give me a hint what went wrong ?
The hypervisor host is a Centos 7.5 system.
