xen-utils-common    3.0.3-0-2


Because of provider I had to change XEN setup from bridged to routing:

#(network-script network-bridge)
#(vif-script vif-bridge)

(network-script network-route)
(vif-script     vif-route)

Now all domains work except HVMs. For first they refused to start.Commenting out line with brctl in /etc/xen/scripts/qemu-ifup helped toresolve this:


#brctl addif $2 $1

Now the problem is that HVM domUs has no connectivity. I've found thisproblem:


9: vif7.0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
   link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff
   inet xx.xx.xx.xx/32 brd xx.255.255.255 scope global vif7.0

The vif for HVM domain has NO-CARRIER but all other non-HVM domains are OK.

Any ideas?

Thanks in advance.
