I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's.
Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are configurations that I set up):
-> eth3
DEVICE=eth3
BOOTPROTO=static
HWADDR=D4:85:64:4B:76:AB
_ONBOOT_=yes
#HOTPLUG=no
#DHCP_HOSTNAME=kdr-3k-4r-3o-07
BRIDGE=br0
TYPE=Ethernet
-> br0
DEVICE=br0
TYPE=Bridge
BOOTPROTO=none
_ONBOOT_=yes
Then I configured new virt. ifaces on VM's (using virsh edit, config is listed below):
<interface type='bridge'>
<mac address='00:16:36:17:62:5d'/>
<source bridge='xenbr0'/>
<script path='vif-bridge'/>
<target dev='vif5.0'/>
</interface>
<interface type='bridge'>
<mac address='00:16:3e:ca:63:39'/>
<source bridge='br0'/>
<script path='vif-bridge'/>
<target dev='vif5.1'/>
</interface>
You can see the default bridge (xenbr0 -> vif5.0) and my new bridge br0 connected to vif5.1.
So, here I got stuck up - when I try tu start a VM (xm create VIRT_SRV), the VM starts booting but hangs up (I can ping it form another srv., but when I try SSH it says "connection refused"). When I remove configuration for vif5.1 the VM starts up normally. I actually managed to start VM with vif5.1 up once, but next time I restarted it, the problem was there :/
Furthermore, I noticed this in the Xen log:

So the boot process goes on regulary until the last line ("Waiting for devices vtpm"). It seems like TPM makes it impossible for VM's to start regulary. When I open the VM's console (with virt-manager) I see the whole boot process but it hangs when it tries to start iface eth2 (attached to the second bridge) ...
Does anybody have a clue why is this happening?
Thanks in advance ..
