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'
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

Hey all again,
I have solved the problem myself. The first tests with RealVNC and
TightVNC don't worked now I tested it with Remmina from an Ubuntu
Desktop and this worked.
Best Regards
