[Xen-devel] Xen 4.1.2 HVM guest realtek nic problems (eth0 8139cp transm
Hello,
While testing Xen 4.1.2 and HVM guests I noticed the following problem
with Fedora 16 HVM guests (using Linux 3.1.0 kernel in the VM):
The errors (call trace) happens pretty much immediately when there's some
network traffic going on..
Simple "yum update" in the VM triggers the problem..

Full guest kernel dmesg attached to this email.
The host is running F16 with Xen 4.1.2 and Linux 3.1.0 dom0 kernel.
Xen cfgfile for the HVM domain:
kernel = "hvmloader"
builder='hvm'
device_model = 'qemu-dm'
name = "f16test64hvm"
memory = 1024
vcpus=1
pae=1
acpi=1
apic=1
vif = [ 'type=ioemu, mac=00:16:3f:03:01:14, bridge=virbr0' ]
disk = [ 'phy:/dev/vg_f16/f16test64hvm,hda,w',
'file:/root/iso/Fedora-16-Final-RC2-x86_64-DVD.iso,hdc:cdrom,r' ]
boot='cd'
xen_platform_pci=0
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'
Using "model=e1000" instead for the vif works OK.. no problems with the
emulated intel nic.
Any ideas what the problem with the emulated realtek nic?
Thanks,
