[Fedora-xen] Virt-Clone Fedora8/Xen 3.1

Wed Feb 13 04:11:23 UTC 2008

Dear List Colleagues:

Wow!  So much traffic on these neat but mysterious tools.  I used the 
'touch' workaround today and got virt-clone working - thank you both to 
christf1 and to Cole!  The relief was literally indescribable when it 
ran (...pressure, what pressure?!)   I have been in touch with Cole and 
he informs me that the latest and greatest version of virt-clone can be 
gotten from the virt-manager devel repository and that this version does 
not need the 'touch' work-around.  For those of you who have not used 
virt-clone - when it finally works it is really great and as cloning is 
of vital importance to the project I am working on, many thanks to all 
who contribute to the virt-manager tools!

In a previous post, on this thread today, it was mentioned that some of 
my results were unduplicable on the usage of switches such as "-f" and 
"--file" - interestingly, yesterday, the same day I experienced those 
problems I was unable to duplicate some of them, myself, when I went 
back to them.  I do not know why this was/is the case or what happened, 
there  the results I posted were copied from actual terminal windows 
where they had run.  I am willing to run a set of tests against my 
machine with virt-clone and send them off to anyone interested in its 
functionality or lack thereof.  I think that this is an important tool 
and I am willing to do whatever I can to help develop it.  I have 
certainly found it to be 'touchy.'

Cole has asked me, as a repository using newbie  - who had a lack of 
success gaining access - to report on my experience of trying to get 
stuff out of the repository and I will do so, shortly, and report my 
experience so others can benefit from my efforts to gain competence and 
my report on how this is done - some steps do seem to be skipped in the 
instructions on that site!  Thanks, again to Cole for pointers on what 
was going wrong for me, there.  It was great to see my questions about 
LVM and virt-clone answered today, before I could even ask them myself!

Best,

Petrus
