Re: [libvirt] [PATCH v3 1/3] Introduce QEMU_CAPS_ARM_VIRT_PCI
Hello!
Is there a way how we could detect this according to the actual
presence
of the PCI bus for the ARM machine? A certain device type that can be
queried rather than relying on a version check.
I looked at the code you suggested. As far as i could understand, it actually parses an
output of
"qemu-system-blah -device ?" plus some extras. And this command lists all
devices that this qemu
version knows, and not only what can be attached to a particular machine.
I browsed through the history of qemu patches. Actually, "gpex-pcihost" device
was implemented
together with adding it to 'virt' machine. So, i could query for this flag and
count it as
capability. But - it only says that qemu knows this device in principle. It does not say
that this
device is really a part of virt machine. Will it be acceptable ?
