Hello again guys,
This thread was very interesting for me, so, I've decided do some tests,
and I would like to share with the list (and hope to kill some
doubts...)
So, I have running on my desktop (Dell Optiplex 745) one Ubuntu Hardy,
on my sda2, so:
- dd+netcat to copy my device into my XenServer running RHEL5;
- create one new LVM file, and particione it (/ and swap);
- mount the image and copy the files to LVM device;
- adjust files like fstab and mtab (/ its now sda1, not more sda2)
and after, I've used the Igor's idea:

I never was think on this before, great idea! Before kill myself using
Xen, I've used the old and good qemu to fix my image (reinstall grub and
etc) :-D
After this, I've just put my working qemu's image inside Xen, like this:
name = "teste"
uuid = "da7371c1deaf8280213a0534b43da4ca"
maxmem = 500
memory = 300
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
sdl = 0
vnc = 1
vncunused = 1
keymap = "en-us"
disk = [ "phy:/dev/Vol_LVM/teste,hda,w",
"file:/iso/ubuntu-7.10-desktop-i386.iso,hdc:cdrom,r" ]
vif = [ "mac=00:16:3e:1f:86:70,bridge=virbr0,type=ioemu" ]
serial = "pty"
And it's working like a charm, but:
1-) Should I use hda or sda on xen config file? And on domU (grub,
fstab)... must be hda or sda?
2-) I'm getting a lot of errors like this on my dmesg/messages... what
can I do to fix this?
