As far as I am aware the vfb option is only available for pv domains. I think to
recall that I had a problem starting a domU if the VNC ip was wrong, this may
also apply if you try to have two domUs on the same VNC port
(''vncdisplay'') try using port 10 for one domU and port 11 for
the other.

Emne: [Xen-users] config file conflict??
I think it has to be something trivial, but I cannot start 2 windows servers at
the same time on the same dom0.
If I start server 2008 first I can’t start 2012, if I start 2012, I can’t start
2008.
The failure is:
libxl: error: libxl_device.c:470:libxl__wait_for_device_model Device Model not
ready
xl: fatal error: libxl_create.c:535, rc=-1: libxl__confirm_device_model_startup
The config files are almost exactly the same with the exception on one using
cpu2 and the other using cpu3, and one using a physical disk and the other a
virtual one.
2008:
kernel = "/usr/lib/xen/boot/hvmloader"
builder=''hvm''
memory = 1024
# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
shadow_memory = 8
name = "server2008"
vfb = [ ''type=vnc,vncdisplay=10,vncpasswd=xxxx'' ]
vif = [ ''mac=00:16:3E:33:5E:F6, bridge=xenbr0'' ]

I suspect this is your problem. Try adding vncdisplay=10 to one domain and =11 to the other (or the distinct display numbers of your choice). Unless by vncunused=0 you were trying to disable vnc, in which case you want vnc=0 in both cases. See xl.cfg(5) for more details of the vnc* options.

I had changed the 10 to 11 on vnc the other day, to no effect. The fix was vncunused=1. See I knew it was something simple I was overlooking.
