VM won't boot - xc_dom_do_gunzip: inflate failed

Issue

VM startup is failing with the following error:

Error: (1, 'Internal error', 'xc_dom_do_gunzip: inflate failed (rc=-5)\n')

Environment

All OnApp versions

Resolution 1

SSH into the HV and run the following command to verify this:

df -h

If /root is full, clear some space on the HV and try to boot the VM again.

Cause 1

This typically indicates that the partition /root that sits on the Hypervisor is full.

Resolution 2

Roll back a VM to the older kernel or restore the initrd file from the backup.

Cause 2

This issue might also happen due to the corrupted initramfs file inside the VM.

Boot a VM into recovery mode and check the image by issuing gzip -t /boot/initramfs.img.
