[pve-devel] applied: [PATCH qemu-server] use new pcie port hardware

[Dmitry Petuhov]

Under Windows 7 I've just hit bug of q35-4.0 that timer runs few times 
faster than it should. See 
https://bugzilla.redhat.com/show_bug.cgi?id=1704375

Had to switch machine type to i440fx from q35 to workaround it.
