(Kernel Linux 2.6.35-22-generic GNOME 2.32)
from the terminal, kvm results in
Starting SeaBIOS (version pre-0.6.1-20100702_143500-palmer)
Booting from Hard Disk ...

Booting from Floppy ...

Now I have installed mint 10 as a dual boot with 3 physical partitions of SSD:
/dev/sda1 windows 27.6GB ntfs
/dev/sda2 /boot 0.5GB ext4
/dev/sda3 extended 27.8GB ext4
/sda5 linux-swap 5.6GB
/sda6 / 15.8GB
/sda7 /home 6.5GB these last three are logical partitions of sda3
Surfing the intertubes I found the following regarding VMs on logical volumes:

Here is the relevant post, it may be correct and I do not follow or a red herring.
Any help in getting kvm to run on mint 10 would be appreciated. - javanero

=================================================================Unfortunately this solution does not work; I get the same boot error as before.
I´ve been googling away and I think I have identified the source of my confusion and a solution the problem. I will try to summarize for the Convirt community what I´ve learned:
1. Having successfully created logical volume-based VMs, I now want the freedom to mount and manipulate those volumes (while the VM is shut down, of course.)
2. I can´t mount the logical volumes that are created. If I create the VM images as RAW (or convert an existing VM image to RAW using qemu-img), then I can mount the RAW image using a loop with offset.
3. It seems that source of my problem is this: since there are multiple partitions (boot, /, swap) in the image that is device-mapped to the logical volume (not sure if that is semantically correct?), we cannot simply mount it as one would a normal logical volume. (cf. http://www.howtoforge.com/forums/showth ... p?p=164751)
4. One of the responders to the discussion thread suggests using kpartx to create loopback devices for each of the partitions found on the physical device. I will be trying this ASAP and sharing my findings here.
5. As a further possibility...the utility qemu-nbd (for some distros it may be known as kvm-nbd) is capable of exporting a qcow2 image as a network block device. (cf. http://blog.loftninjas.org/2008/10/27/m ... sk-images/.) The utility has an option for specifying a single partition to expose, or it seems logical that once a client has connected to the network block device kpartx may be used to create loopback devices for each of the partitions contained in the image.

I will be experimenting with this over the weekend. However, I would much appreciate any feedback or advice from the community before my next report.
