USB Drive Crashes VM

vizsla · May 22, 2020

I have Proxmox running a CentOS VM and two Linux Containers for a UniFi Controller and UniFi Video. I've included my VM configuration below. The system that runs on this VM has a nightly backup process that saves to a USB flash drive. As you can see in the config, I pass a USB port through to this VM. This has worked for 2.5 years, but recently when the USB flash drive is unplugged to be switched out for the other USB flash drive, the VM locks up. Once this happens, I can't access it through Proxmox VNC and the workstation application that interfaces with the system on the VM loses connection, so it appears the VM is completely crashing/freezing when the USB flash drive is unplugged. After stopping and starting the VM, the backup to USB process works and I've included a screen shot that Proxmox sees the USB flash drive on the port I have passed through to the VM. However, the moment the USB flash drive is unplugged, the VM crash happens again. Can I get some help troubleshooting this?

do you see any log messages in the host/guest log?

Not much, but maybe I'm not looking in the right places? Here is what I have. With the Cent OS VM was running perfectly fine after booting it with the USB flash drive already inserted, I unplugged the USB flash drive and got the following log.

Code:

May 25 13:33:21 pve kernel: [310443.098278] usb 2-3: usbfs: usb_submit_urb returned -19
May 25 13:33:21 pve kernel: [310443.308499] usb 2-3: USB disconnect, device number 4

At this point, the Cent OS VM has frozen or crashed. The workstation applications that use the server have stopped working. The Proxmox console no longer works and any commands I type into the Monitor come back as failing. Example logs of me trying to connect to the VM:

Code:

May 25 13:34:46 pve pvedaemon[3674]: VM 900 qmp command failed - VM 900 qmp command 'human-monitor-command' $
May 25 13:34:54 pve qm[27135]: VM 900 qmp command failed - VM 900 qmp command 'change' failed - unable to co$

If I STOP and START the Cent OS VM again without the USB flash drive plugged in, the VM boots but then freezes/crashes right when I plug the USB flash drive into it. The VM only seems to work now with the USB flash drive if I have the flash drive plugged in before I start the VM. Here's the log of starting the VM with the USB flash drive plugged in.

Code:

May 25 13:45:36 pve pvedaemon[29257]: starting vnc proxy UPID:pve:00007249:01DAD190:5ECC1250:vncproxy:900:ro$

I had been successfully using pve5-usb-automount in conjunction with hot swapping this USB flash drive with the Cent OS VM. When PVE 6.x broke this USB automount script, I could no longer plug in my USB external hard drive into a separate USB port for backup purposes, but my Cent OS VM was still working with hot swapping USB flash drives into the single USB port that is mapped to the VM. Not until around May 18 did the USB flash drive start freezing / crashing my Cent OS VM. I had run the usual "apt update" and "apt dist-upgrade" on the PVE server the day before, so I'm guessing that had something to do with it.

Finally, I have since replaced pve5-usb-automount with pve6-usb-automount, but that didn't help with my issue. I have removed pve6-usb-automount now and still no improvement. I'm mentioning this, because I thought it would be related, but it doesn't really seem to be, since it worked fine for a long time and it doesn't seem to me anything related to this changed when my VM freezing issue started occurring.

Here is the Messages logging at the point that I disconnected the USB flash drive and the CentOS VM froze/crashed:

do you see any log messages in the host/guest log?

None of the logs jump out at me as being helpful in troubleshooting this issue, but I could be missing something.

Yes, I faced the same problem as you. VM freezes if you pull out the USB device that the OS is accessing. Everything used to work fine before. The only way that I have found so far is to correctly stop the call and disconnect the device from inside the guest system.

I still haven’t figured out how what’s causing this.

Steffenprox · Jun 7, 2020

I got the same issue since last update.

Hello. I have the exact same problem on my PVE server. When I disconnect a serial port USB device (FTDI) while used, the guest crash.
I have found nothing in the logs (host and VM). The problem occurs on a Linux guest, FreeBSD and Windows as well.
This problem has appeared when I upgraded Proxmox from 5 to 6. Seems to be related to KVM maybe?

Is there any way to downgrade Proxmox while this gets fixed?

I'm not entirely sure anyone has acknowledged this as an issue to be fixed yet.

I think you would downgrade using something like apt-get install proxmox-ve-6.1-2, but you'd want to do a little more investigating before taking my quick comment. I have no clue what concerns there might be about that breaking something.

This only downgrades Proxmox's meta package. We'd need to downgrade qemu, but there are many dependencies, so I don't think it's possible. I'll have to wait I guess :/

It doesn't freeze anymore. Use at your own risk though.

Dang. I just installed the following, rebooted PVE, and then tested this... and pulling the USB drive out of the server still locked up / froze / crashed the Linux VM that has the USB drive passed to it. Do you know why you also got pve-kernel-5.4.44-1-pve: 5.4.44-1? Edit: Looks like I just already had that installed is all.

vizsla · Jul 8, 2020

I updated to pve-kernel-5.4 (6.2-4). Ran my first test this morning by restarting my server with the USB flash drive plugged in. My VM recognized the flash drive. I unplugged it, the VM didn't freeze/crash, and I could see in the CentOS VM that it had been disconnected. I then plugged my next rotation USB flash drive in and CentOS showed it mount and the VM did not freeze. I'll keep trying this to see if the issue is gone or if this was a fluke.

Shadow2091 · Jul 8, 2020

Checked with the latest kernel version - the VM still breaks if you remove the mounted USB drive
