RE: NVMe drive PCI passthrough and suprise hotplug
[AMD Official Use Only]
Hello Peter,
Thanks for your response, we will try with the latest fedora and possibly also with the
latest libvirt
and re-test.
Will reply with attached debug logs as mentioned below in case we still face the same
issue
with re-testing.
Thanks,
Ashish

Well, I hope it's okay to use it for libvirt officially too ;)
Hi,
I am using Fedora 33, with the following KVM, qemu and libvirt versions:
Note that Fedora 33 is already end-of-life, it would be great if you can re-test with a
more recent version
QEMU 5.1.0
libvirt 6.6.0
specifically this was released 1.5 years ago
KVM 5.14.18
We have done pass-through of a PCIe NVMe device to the guest running
on FC33 using either virt-manager or virsh and then we do the
hot-unplug of the device while it is attached to the guest.
The device is no longer seen on the guest hardware device list on
virt-manager and then we hotplug the device again and we are able to
use it on the Host, but when we try to re-attach it to the guest, we get the following
error message:
Requested operation is not valid, PCI device 0000:c4::00.0 is in use
by driver QEMU, Domain fedora 33.

Unfortunately the tracing you've done doesn't really help in seeing what gone
wrong in libvirt.
Please attach debug logs per
