Subject: [pve-devel] [PATCH qemu-server 0/3] fix #3258: check for in-use pci devices on vm start
Date: Tue, 5 Oct 2021 15:11:57 +0200 [thread overview]
Message-ID: <20211005131200.791836-1-d.csapak@proxmox.com> (raw)
by having a vmid <-> pciid mapping in /var/run
i did not check if the vm has the pci device really in the config,
but we should not need that, since we remove the reservation again
in the cleanup step.
if wanted we can of course parse the target vms config and check if
the pci device is still configured, or alternatively, ask qmp and or
parse the /proc/PID/cmdline for the pcidevice, but both options seem
too expensive?
Dominik Csapak (3):
pci: to not capture first group in PCIRE
pci: add helpers to (un)reserve pciids for a vm
fix #3258: block vm start when pci device is already in use
