Re: [Xen-users] cloning guests between Dom0's ?



I wrote those steps mainly based on :

http://www.howtoforge.com/linux_lvm
http://www.howtoforge.com/linux_lvm_snapshots

From my experience (short), I was able to clone VM's (SL 47) this way (and backup of course). No problems in particular.
Instead of using tar, dd could also be used (but larger files).

Is there a better way to do this? I'm just a newbie on this strange world, trying to do my best ;-)

Cheers,
N.

Is this correct ? I know the LVM snapshot will give you a "point in time"
image, but won't the DomU have unwritten changes in it's cache - giving you
a very unclean filesystem ?

Changes in cache - yes.
Unclean - yes.
Unusable - No. Well, depends on what fs you use, actually :)

it will be no worse than a server power failure: If you use ext3 (or
any other journaling filesystem that can withstand power failure),
then  it should be able to replay filesystem journal automatically on
mounting to give you a usable filesystem.
