Hi,
I can confirm this failure using 3.0.5-rc2 hypervisor and tools with a 3.0.4-1 2.6.16.38 Gentoo guest on i386.
After dom0 boot, the domU boots fine, vncfb runs fine.
If I halt the domU, I can't boot it again and get this error :
Device 0 (vkbd) is already connected.
All was running fine with 3.0.4-1 hypervisor and tools and same guest/config.
Regards,
Cédric

Is vfb working well lately? I thought I'd test it out on ia64 and it
works great, but only once per boot. If I stop the domain and restart
it, I get the following:
Error: Device 0 (vkbd) is already connected.
To make sure this isn't an ia64 anomaly, I tried it on an x86_64 system.
Same thing, works the first time, reboot the domain and it's broken. I
see someone reported a similar issue last month, but there was no
response:
http://lists.xensource.com/archives/html/xen-devel/2007-03/msg01141.html
The backtrace in xend.log looks like this:
[2007-04-11 15:23:07 2659] ERROR (__init__:1072) XendDomainInfo.initDomain: exce
ption occurred

File "//usr/lib/python/xen/xend/server/DevController.py", line 111, in createDevice
raise VmError("Device %s is already connected." % dev_str)
VmError: Device 0 (vkbd) is already connected.
My domain config file has the following options to enable vfb:
vfb = [ 'type=vnc, vnclisten=0.0.0.0, vncunused=1' ]
extra = "console=ttyS0 xencons=ttyS video=xenfb"
Is anyone able to make this work reliably more than once? Thanks,
Alex
