USB redirection is not supported by this version of QEMU

Support Virtualization
1

I reinstalled my Manjaro OS and now virt-manager can no longer access myQcow2 W10 guest.

When I try to import my disk image I get the following:

Unable to complete install: 'unsupported configuration: USB redirection is not supported by this version of QEMU'

My main hard drive is an SSD, but I have a 1 TB secondary disk in my laptop where the image resides on /dev/sda2.

The disk is mounted on /data in /etc/fstab

UUID=9E8E8B808E8B5027                     /data          ntfs    auto,users,rw,permissions 0 0

I am using Virtual Machine Manager 4.1.0
QEMU emulator version 9.1.0

Is this a known issue?

Is there another version of Qemu available?

Is there an issue with my configuration?

Many thanks.

What do you mean by image? A virtual disk?

What do you mean by import? Reusing the qcow2 virtual disk?

In my experience with virtual machine manager - you need to configure the virtual machine and the import is simply reusing the virtual disk.

This implies that you copy the virtual disk to /var/lib/libvirt/images and ensure the correct permissions - or setup a different storage.

Yes. It’s a qcow2 file as indicated.

The thing is that I have been able to to access it previously, but for some reason it no longer works.

Moreover, if I try to create a new disk, I get the same error.

My 1TB disk is SATA, so I’m a little surprised to see this error.

Unfortunately my SSD is not big enough to copy the Qcow2 image to access it there.

That is strange - but it does point to a generic preference with virt-manager.

Check the Console tab in Preferences of the Virtual Machine Manager window.

On my system I have no issues with setting of SPICE USB Redirection but it appears your system does.

Thanks.

That helped a lot as it made it possible to identify the missing dependencies.

Thanks very much for your time and effort.
