Hi all, I have a network problem:
Dom0 has:
Dom1: linux paravirtualized
Dom2: winxp hvm

It worked well but now winxp can not connect to network:

Dom0 has eth0, lo, peth0, vif1.0 and vif3.0

From Dom0:
[root@localhost xen]# xm network-list WinXP --long
(0
    ((backend-id 0)
        (mac 00:16:3e:3f:54:42)
        (handle 0)
        (state 1)
        (backend /local/domain/0/backend/vif/3/0)
    )
)

[root@localhost xen]# xm network-list Linux01 --long
(0
    ((backend-id 0)
        (mac 00:16:3e:58:56:65)
        (handle 0)
        (state 4)
        (backend /local/domain/0/backend/vif/1/0)
        (tx-ring-ref 109)
        (rx-ring-ref 526)
        (event-channel 10)
        (request-rx-copy 1)
        (feature-rx-notify 1)
        (feature-sg 1)
        (feature-gso-tcpv4 1)
    )
)

[root@localhost xen]# brctl show
bridge name     bridge id               STP enabled     interfaces
eth0            8000.00155880c616       no              vif3.0
                                                        vif1.0
                                                        peth0
