Re: [libvirt] [PATCH v5 2/4] qemu: Add PCI-Express root to ARM virt machine
Hi!
The only negative impact it would have is that
if someone has old QEMU installed at define time and later upgrades to
a QEMU with PCI support before starting the guest, they'll lack the
PCI controller.
This won't actually happen, because together with the missing controller he/she will
not have PCI devices. Attempt to add a device without a bus immediately produces "No
PCI bus" report, and the XML gets rejected. And, right after the upgrade, as soon as
he/she adds some PCI devices to use, the XML will be re-parsed, and PCI bus description
will be added. Because reparsing happens after any change.
So from that POV, maybe we should just clean up the current merged
patch so that it is properly exercised in the test suite by providing
capabilities
I will try to do it soon.
