OEL 6.9 PVM guests on Oracle VM 3.4.3 won’t start

I recently upgraded by OVM to 3.4.3(.1511), but now my Oracle Enterprise Linux 6.9 PVM guests won’t start up any more. They don’t finish the ‘Starting automount’ in the boot / startup screen. It does not fail, it just won’t continue.

There is nothing special in the /etc/fstab I guess… :

/dev/mapper/vg_root-lv_root               /                       ext4    defaults        1 1
UUID=ac367ac9-deea-4d74-8dcc-83e384a9a82b /boot                   ext4    defaults        1 2
/dev/vg_oracle/lv_oracle                  /oracle                 ext4    defaults        1 2
/dev/mapper/vg_oracle-lv_swap             swap                    swap    defaults        0 0
tmpfs                                     /dev/shm                tmpfs   size=3g         0 0
devpts                                    /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                                     /sys                    sysfs   defaults        0 0
proc                                      /proc                   proc    defaults        0 0

Changing to HVM+PV

Switching them to HVM+PV drivers guests does work. I know it’s not a solution, but HVM+PV is the way to go anyway… I always liked the flexible online changing of cores and memory of PVM, but it’s from the 32-bit and non-VTx era. Also Oracle VM and OEL 7 does not support PVM anymore :(
