Re: [Xen-users] Weird bridge problem Xen 4 + Debian Squeeze + HVM

[Francisco Javier Funes Nieto <esencia@xxxxxxxxx>]

Without the VM-HVM running...

root@debian:~# brctl show

bridge name     bridge id               STP enabled     interfaces

eth0            8000.002215e17c2f       no              peth0

VM-HVM Running:

root@debian:~# brctl show

bridge name     bridge id               STP enabled     interfaces

eth0            8000.002215e17c2f       no              peth0

                                                        vif1.0

If I use type=paravirtualized in the vif statement and add to the iso the GPLPV drivers (with nLite) the network works in the HVM domU (WinXP) but the default type=ioemu doesn't works.

With Xen 3.4.2/Lenny dom0 it works flawlessly !! But Squeeze/Xen4 doesn't.

Any ideas?

you specify eth0 as the bridge interface?
does eth0 is really a bridge?

what's the output of brctl show?
