Xen 4.1.2 PVHVM guest with Linux 3.1.0 network problem, empty MAC address (all zeroes)

["Pasi Kärkkäinen" <pasik@iki.fi>]

Hello,

While testing Fedora 16 Xen PVHVM guests I noticed the following problem:

When starting F16 PVHVM guest I can see the vifX.0 and tapX.0 interfaces appear on dom0, 
but after the guest kernel (Linux 3.1.0) starts and loads PVHVM drivers the 
vif/tap interfaces disappear from dom0.. 
so the bridge in dom0 doesn't have any vifs/taps connected to it anymore.

Has anyone seen that behaviour? 

I bet that's also the reason why eth0 inside the PVHVM guest 
has a MAC address with only zeroes in it: 00:00:00:00:00:00.

If I disable PVHVM with "xen_platform_pci=0" in the domain cfgfile
then network for the guest works OK using the qemu-dm emulated nic.

PVHVM guest cfgfile:

kernel = "hvmloader"
builder='hvm'
device_model = 'qemu-dm'
name = "f16pvhvm"
memory = 1024
vcpus=1
pae=1
acpi=1
apic=1
vif = [ 'type=ioemu, mac=00:16:5f:03:01:15, bridge=virbr0, model=e1000' ]
disk = [ 'phy:/dev/vg_f16/f16pvhvm,hda,w', 'file:/root/iso/Fedora-16-Final-RC2-x86_64-DVD.iso,hdc:cdrom,r' ]
boot='cd'
xen_platform_pci=1
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
sdl=0
vnc=1
vncpasswd=''
stdvga=0
serial='pty'
tsc_mode=0
usb=1
usbdevice='tablet'
keymap='fi'

Some output from inside the PVHVM guest:

"xm log" doesn't have any errors.
Any ideas how to fix this? Why do the vif/tap devices disappear from dom0?

Thanks,
