The first problem is, that it seems to be a tool to create persisten virtual
machines, e.g. virtual servers, but most of the time I only want to boot a
live cd, e.g. a Fedora one. But virt-manager seems to demand an virtual HD
drive. I only tested it twice or so, but it looked not promising.
The next version of virt-install will support this explicitly. I am
reliably assured that it should work in qemu & Xen.
Support is not there yet in virt-manager.
What I did so far was creating a new machine with a Fedora Live CD
Image and
booted it. When I hit the Pause button, it appeared to be pressed, but
nothing happened. The machine still responded and the following error
appeared on the commandline, where I started virt-manager:
-------------
libvir: QEMU error : operation failed: suspend operation failed
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/console.py", line 389, in
control_vm_pause
self.vm.suspend()
File "/usr/share/virt-manager/virtManager/domain.py", line 365, in suspend
self.vm.suspend()
File "/usr/lib/python2.5/site-packages/libvirt.py", line 350, in suspend
if ret == -1: raise libvirtError ('virDomainSuspend() failed', dom=self)
libvirt.libvirtError: virDomainSuspend() failed operation failed: suspend
operation failed
--------------
This is a bug. Do you know what version of libvirt & virt-manager this
happens with? Suspend _ought_ to work with QEMU with libvirt >= 0.2.0.
Then when I shut down the machine and clicked on "run", it
did not boot the
ISO Image I selected while creating the machine, but only complained that it
could not boot from HD (which is true, because I did not install anything to
the HD)
Then I wanted to delete the machine, but the "Delete" button was still greyed
out, even when I shut it down (Imho it should be available all the time and
provide a warning that the machine needs to be shut down before it can be
deleted). When I closed virt-manager and opened it again, then I was able to
delete the machine.
But I cannot find a way to add an iso image to the machine or make it boot the
iso image I selected at creation time.
I haven't played with live CDs & virt-manager at all, but I'll have a
go. What live CD were you trying?
Also the network selection seems not to work, when I want to add a
network
interface, I can choose between virtual and shared device, but both only have
an empty list, where I have to select something to be able to click
on "Forward".
This is another bug. If you get me the version of virt-manager, I'll
look into it.
I guess you cannot help here very much, because it seems to me that
virt-manager just needs a lot of coding, to become as userfriendly as
VirtualBox is.
