Just a guess, as you already tested many things
I remember in the past I had problems when the boot partition was not
marked as active.
I don't know if still relevant.
Could you verify, if /dev/sda is your boot disk, with the command

fdisk -l /dev/sda
?

Something like this with the star in the "Boot" column:

[root@ractorshe ~]# fdisk -l /dev/vda

Disk /dev/vda: 10.7 GB, 10737418240 bytes, 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000cb2a3

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048    20971519    10484736   83  Linux
[root@ractorshe ~]#

BTW: are you using virt-manager to configure/run your VMs? Or direct virsh
commans or what?

HIH,
Gianluca
