Hi community, new to harvester and was trying to spin up an ubuntu VM instance after installing the OS on the bare metal. However, I ran into the following issues:

0/1 nodes are available: 1 pod has unbound immediate PersistentVolumeClaims.

I did some basic hardware checks, such as disk storage (the machine has 512 nvme for OS and 4T for VM data), but still have no idea why it still give me this error. Anyone know what could go wrong here? Everything is default out of box for now. Really appreciate it!🙏

the pvc claim associated with this vm cant be satisfied

you may want to check the PVCclaims in the namespace as VM

the associated launcher pod will have the pvc details if needed

hmmm, this is freshly out of box after the installation, everything is default

is it possible because hardware issue, i.e. I am installing harvester on a consumer motherboard i.e. ROG with an AMD ryzen cpu

is there any place I can get this information for debugging?

the associated launcher pod will have the pvc details if needed

kubectl get pvc -n default

✅ 1

or you can just generate a support bundle and i can look at it

great! let me spin up the machine and get back to you, thanks!

@great-bear-19718 Finally figured, turned out I forgot to turn on the KVM supports of the AMD CPU, which indirectly detach the volume whenever I start the VM and thus caused this problem. Once I turned the KVM support of AMD in BIOS, then it worked fine.
