Enabling VM Service causing USB Flash Drive to go offline

[bisk]

I'm having an issue when I enable and start the VM Service, my USB Flash Drive starts to report offline and becomes unreadable.  As suggested in the GUI, I have attached a diagnostic bundle from after enabling the service and the flash drive going offline.

 

This issue started happening after I had a faulty CPU in my system.  I have replaced the CPU and everything runs fine until I enable the VM service.

Check the config for all VMs, the USB flash drive/controller may be passed-through to one of them.

Without being able to start the VM service, how can I do that?  From what I can remember, I wasn't passing the flash drive or a USB controller into the VMs, but I was passing some USB devices.

Is this your flash drive?

 

Bus 001 Device 005: ID 0951:1666 Kingston Technology DataTraveler 100 G3/G4/SE9 G2/50

 

You have it defined in the JasonVM.

 

mv /usr/local/sbin/qemu /usr/local/sbin/qemu.old

 

This will allow you VM manager and the VMs will not autostart.

 

edit the VM to remove this section.

 

<hostdev mode="subsystem" type="usb" managed="no">

<source startupPolicy="optional">

<vendor id="0x0951"/>

<product id="0x1666"/>

</source>

<address type="usb" bus="0" port="1"/>

</hostdev>

 

mv /usr/local/sbin/qemu.old /usr/local/sbin/qemu

 

Now you should be able to start your VMs.

Interesting that a flash drive is being redirected, I honestly don't remember doing that, but I guess I did 🤷‍♂️

 

I started the array with VM Manager disabled

Ran "mv /usr/local/sbin/qemu /usr/local/sbin/qemu.old"

Enabled VM Manager

Edited JasonVM in XML View to remove the section suggested, but when I try to save the changes I'm getting the following error - "VM creation error.  Cannot check QEMU binary /usr/local/sbin/qemu: No such file or directory" and then the VM is removed from VM Manager.  I was able to restore my VM Metadata since I've got a backup though.

 

Here are the steps that I took to get things working again

Disabled VM Manager

Started the array

Ran "mv /usr/local/sbin/qemu /usr/local/sbin/qemu.old"

Enabled VM Manager

Disabled Autostart on all of the VMs

Stopped the array

Rebooted

Started the array

Edited JasonVM in XML View to remove the section suggested

I was able to manually start the VMs now

Enabled Autostart on the VMs that I wanted to start with the array

 

Thanks for the assistance in getting me back up and running!
