[Libvir] Use virsh to monitor qemud
by Fabian Deutsch
Hey,
I jsut installed Fedora 7 and tried to install some guests and it worked
like a charm. I use qemu for full virtulization.
A couple of minutes later i stumbled across libvirts virtsh. But now I
wonder how I cna use virtsh to connect to qemud - all I get is something
like: "Can't connect to hyperisor."

[Libvir] SOLVED Re: cannot use vncviewer and VMM graphics console to access HVM guest on RHES 5
by Glen Deem
Thanks to Igor Chubin (spasibo) and Richard Jones, the qemu vnc server
was listening but I did not connect to its proper port (why libvirt
doesn't use <IP>:<domU id> kind of vnc connection and restricts the
server to local host only by default?).
Regards,
Glen

Hi Dan,
I'm with you about the VNC authentication.
But I still don't understand the logic behind assigning HVM displays.
Instead of clear "domU ID is the display number" (vncunused 0), the
Virtual Machine Manager assigns vncunused to 1 and then calculates the
5900+ port, I suppose depending on what port is not occupied (BTW
where exactly is this code in the source, please?).
Why is that? And how am I suppose to find out what that port number is
if I'd want to connect to a VMM-created vm manually with my vnc
client?
Thanks,
Glen

[Libvir] cannot use vncviewer and VMM graphics console to access HVM guest on RHES 5
by Glen Deem
Hi all,
I've created an HVM guest under RHES 5 (Xen 3.0.3) using "xm create"
but I cannot access it with vncviewer.
The Virtual Machine Manager also informs about graphics console unavailability.
What am I doing wrong, please?
I do
> vncviewer 123.456.789.123:4,
where 4 is the guest id.
This is the xm config file is:
name = "hvmGuest"
builder = "hvm"
memory = "500"
disk = [ 'file:/var/lib/red-hat.img,hda,w', ]
vif = [ 'type=ioemu, mac=00:16:3e:34:3b:ba, bridge=xenbr0', ]
device_model = "/usr/lib/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=1
vncunused=1
apic=1
acpi=1
pae=1
vcpus=1
serial = "pty"
on_reboot = 'restart'
on_crash = 'restart'
Thanks a lot in advance.
