I am planing to move form OVM to hyper-v, in-order to do the migration, I shutdown OVM (VM is using Oracle Linux 7.2) normally, then exported the appliance from OVM Console, move it to Windows machine then convert it to vhdx file using StarWind V2V Image Converter.
When I start the converted VM and try to use (Oracle Linux Server (3.10.0-327.el7.x86_64 with linux) 7.2 everything is working fine without any issue, how ever if I use (Oracle Linux Server (3.8.13-98.7.1.el7uek.x86_64 with unbreakable Enterprise Linux) I got Dracut rescue mode with the following error message (shown in the attached image)
enter image description here



I searched from some solution regarding this issue like executing dracut -f, edit /etc/fstab manually (note the file appears fstab.empty creating a file manually did not help at all), check if I can edit /etc/default/grub but the file dose not exist either, removing the corrupted kernel using rpm -e I got the following error "kernel dose not exit" but if I try to install it using yum or rpm it failed since the kernel exist, I have tried to fix the LVM using the solution on Redhat portal, but I got the following error message "/run/lvm/lvmetad.socket: connect failed: no such file or directory" (attaching a screen shot)
enter image description here
For further troubleshooting I opened "/run/initramfs/rdsosreport.txt " file and found it contains errors as shown in the screen show below
enter image description here
I tried to execute the commands bellow but it filed /bin/sh no such file or directory



mount --bind /proc /mnt/sysimage/proc
mount --bind /dev /mnt/sysimage/dev
mount --bind /sys /mnt/sysimage/sys
chroot /mnt/sysimage
dracut -f
exit
cd /
sync
telinit 6


Please advise what I have missed during my troubleshooting. Thanks

  • It looks like the 3.8.13 UEK initial ramdisk doesn't have the drivers for the (virtualized) disk drivers, so can't see any storage. If booting 3.10.0 does work, force reinstalling 3.8.13 UEK when booted. That should rebuild the initial ramdisk image with the correct drivers.
