Need help. I'm still a bit of a noob. Have Procmox set up with two VM's.

Tried to pass through PCI to one of the VM's and now on reboot I can't access Web GUI.

Is there a way to remove that hardware option via command line?

I think I need to remove the "hostpci0: 00:17" from my qm config 101

Hmm, what did you pass-through, the network card? As else it'd seem a bit weird if the webinterface broke due to some (failed) GPU pass-through.

Try:
Bash: 
qm set 101 --delete hostpci0

I have no idea what caused it but something is stopping me from loading GUI since thing to pass it through. Maybe the same controller that I the OS runs on?

I tried your command and got: "unable to open file '/etc/pve/nodes/proxmox/qemu-server/101.conf.tmp.2536' - Input/output error"

Hmm, seems your root FS has some issues, maybe the actual cause is bad/broken disk?

Can you post the output of the following command so that we can see what PCI(e) controller/device you actually assigned to the VM:
lspci -vv

Also, is the VM currently running?
qm status 101 --verbose

I am getting a lot of Buffer I/O error on device dm-1, logical block
 
OMG so I finally was able to recover GUI by turning off autoboot for the VM very quickly before it started to corrupt, now I just need to figure out how to get it working again!


Code: 
qm set 101 ---autostart 0
