Host - Ubuntu 12.04.
Virtualization - KVM.
Disks - LVM.

The installation of the guest system was completed without errors.
After reboot, the following error is displayed:

Booting from Hard Disk...
Boot failed: could not read the boot disk

Booting from Floppy...
Boot failed: could not read the boot disk

No bootable device.

Connected SystemRescueCD - all disks are found and read.

disks are found and disks are read - does not mean that they are booting from them. maybe in the “bios” of the virtual machine it is written to load cd | dvd only? I don’t know how it is in Linux, but in virtualbox / ESXi / Hyper-V this is a separate parameter - I have one screwless virtual machine, which always slips flash drives, then iso, then all sorts of rubbish into the boot.

There was the same problem. In the 'os' section, ironically added boot dev

 <os>
    <type arch='x86_64' machine='pc-0.12'>hvm</type>
    <boot dev='hd'/>
  </os>

Might be useful to someone in the future.

Better like this

<os>
  <type>hvm</type>
  <boot dev='network'/>
  <boot dev='cdrom'/>
  <boot dev='hd'/>
  <bootmenu enable='yes'/>
</os>
