Hi,

 

I just upgraded the xen-hypervisor-3.2-1 package in Debian etch from the backports (3.2.1-2~bpo4+1) and now my HVM instance won't boot any more.

The error message in the log is:

 

-c config qemu network with xen bridge for

tap0 xenbr0

bridge xenbr0 does not exist!

/etc/xen/scripts/qemu-ifup: could not launch network script

Could not initialize device 'tap'

 

I have

 

vif = [ 'type=ioemu, bridge=xenbr0, mac=00:16:3E:36:83:46' ]

 

in the guest's config which worked fine before.

 

If I comment out

 

brctl addif $2 $1

 

in

 

/etc/xen/scripts/qemu-ifup

 

the guest boots, but then it doesn't have any networking.

 

Does anybody know how to fix this?

 

Kind regards,
