[Xen-users] cannot enable sound on domU (centos5.1) and cannot change virbr0 bridge to xenbr0 bridge
Hi all,
my dom0 is centos5.2 and domU paravirtualized is centos5.1
I can play sound on dom0 but not in domU (name: gasphar), moreover I use
wifi as my inet connection and on installing domU cento5.1, I used
virt-manager.
I know that libvirtd made virbr0 and when changing to xenbr0, I cannot
connect to internet but ssh to dom0 is fine!
so how do I enable sound device on domU and changing to xenbr0?
so please examine and analyze my case:
Thank you before
