.... I have a 64-bit CentOS 5.6 VM running on a 64-bit FC14 host.
Actually, I *HAD* a 64-bit CentOS 5.6 VM :-) .... After a read of the
virt-install man page, I concluded that I could lose the current VM (but
*NOT* its HDD image) & recreate it fairly easily w/ the right combo of
arguments to virt-install. The proceedings:

This will overwrite the existing path
'/home/VMs/CentOS.5.6-64bit-VM/disk.img'
Do you really want to use this disk (yes or no)
no
What would you like to use as the disk (file path)?
quit
How large would you like the disk (quit) to be (in gigabytes)?

i.e. I chickened out at the ominous-sounding message about wiping out my
hard-won disk image .... I thought (from the man-page) that the
'--import' command would skip any attempts at installing anything,
define the VM from the arguments supplied, & boot it from the
already-prepped disk image .... Am I right here ? If not, is there a
recommended way to re-create my VM (mostly) from the extant disk image
w/o having to redo whatever initialization I have done so far (setup a
user, install compilers & dev.env., install Intel compiler, etc.) ?
Also, is there a recommended way for the host to copy that disk image
somewhere so I can try to reuse it if my future attempts at re-creation
don't pan out ? TIA ....
