VNC console only shows black screen on HVM guest running on Xen 4.1 with Ubuntu 12.04 as Dom0
Hello all,
I have a problem getting a working VNC console for HVM guests on Xen
4.1. When I start the DomU with xm create everything is fine the DomU
runs and in xm list it has the running state but when I try to connect
to the VNC console to install an operating system (Ubuntu and Debian I
have tested) the VNC viewer only shows a black screen. So I searched in
the logs and found a log entry where I think that this is the problem:
xen be: console-0: xen be: console-0: initialise() failed
initialise() failed
It''s in the qemu-dm log file of the DomU. I have put all logs (xend,
xend-debug, xen-hotplugpath and qemu-dm) put into the attachment of this
mail.
Here also is my actual configuration for the DomU:
kernel = "/usr/lib/xen-4.1/boot/hvmloader"
builder = "hvm"
memory = 4096
shadow_memory = 16
name = "mailer1"
vif = [
''type=ioemu, bridge=xenbr0, mac=00:50:56:00:04:25''
]
acpi = 1
apic = 1
disk = [
''phy:/dev/vmdisks/mailer1,hda,w'',
''file:/isos/debian-6.0.5-amd64-netinst.iso,hdc:cdrom,r''
]
device_model = ''/usr/lib/xen-4.1/bin/qemu-dm''
boot="dc"
sdl=0
vfb = [
''type=vnc,vnclisten=127.0.0.1,vncunused=1,vncpasswd=sOnlEn3'' ]
serial=''pty''
usbdevice=''tablet''
on_reboot=''restart''
on_crash=''restart''
And here the output of xm dmesg:

All logs are in the attachment as normal text files. The Dom0 is a
minimal Ubuntu 12.04 Precise Pangolin and Xen is Version 4.1.2
Would be greate when someone has an idea and can help me. I think that
the VNC console is not attached correct but I don''t understand why.
When
there are questions for other logs or more info please say.
Best Regards
