listing vms trows a segfault

[alsotoes]

Hi @gmeghnag
Running the following on an openshift-cnv must-gather throws the following error.

$ omc get vms -A
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x198 pc=0x3fe4a3a]

Expected behavior will be a list of vms running, like the following.

$ omc get vms -A
NAMESPACE NAME AGE STATUS READY
default fedora-test123 53d Running True
default fedora-vm 53d Running True
default ubuntu2404 53d Running True

or this

$ omc get vms
resource type "vms" not known.

If is not yet implemented, I've already created this other issue as RFE #199

Let, me know if you need any other data.

Cheers.
