[Xen-devel] Error: Device 0 (vkbd) is already connected.

[Alex Williamson <alex.williamson@xxxxxx>]

Hi,

   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:

The backtrace in xend.log looks like this:

[2007-04-11 15:23:07 2659] ERROR (__init__:1072) XendDomainInfo.initDomain: exce
ption occurred

    devid = self._createDevice(devclass, config)

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
