[Xen-users] PV networking issue in 2.6.38.6 and 2.6.39-rc7

[Mario <mario@xxxxxxxxxxxxxx>]

Hey everyone,

I have been trying to make Xen-4.1.0 work on kernels mentioned in the 
subject, without much sucess. HVM guests are not affected, only PV.
Error that i see in dmesg on the domU:
XENBUS: Timeout connecting to device: device/vif/0 (state 1)

ifconfig -a on domU shows MAC address: 00:00:00:00:00:00

dom0 doesn't have any vif/tap interfaces assigned to domU when i do 
brctl show or ifconfig -a
I don't see any errors worth mentioning in /var/log/xen, except mybe 
these two:
/tmp/SBo/xen-4.1.0/tools/ioemu-qemu-xen/hw/xen_blktap.c:628: Init blktap 
pipes
Could not open /var/run/tap/qemu-read-2

Problem goes away when i boot 2.6.34.7 (it is the last kernel that i 
have built with gentoo rebased patches).
If there is something i can do to help debug this please do let me know.


Best regards,
mario
