Just to clarify, prlctl clone seems to work (it makes a new container from the
source container) but I'm guessing prlctl clone --template doesn't do what I
was hoping it did. I as hoping it made a pre-created OS Template and dropped
it into /vz/template/cache/{name}.plain.ploopv2.tar.lz4 but that does not seem
to be the case. I'm guessing it makes some new meta-data definition or
something. So currently I'm baffled... but at least I can use clone. :)
Here's what I tried:
prlctl clone {ctid} --template --name {new-name}
It made a new container that shows up with "vzlist -a" but oddly not with
"prlctl list --all".
I tried to turn the new container's file structure into an new cached OS
Template by:
1) cd /vz/private/{new-ctid}/root.hdd/
2) tar cvf /vz/template/cache/{name}.plain.ploopv2.tar .
3) lz4 -9 /vz/template/cache/{name}.plain.ploopv2.tar
That was the best monkey-see-monkey-do attempt I could muster but it didn't
seem to work as when I tried to create a new container using my manually
constructed OS Template it gave me the following error:
- - - - -
Creating the Virtuozzo Container...
Failed to register the CT: Operation failed. Unable to get appcache tarball
name for f04da639-c801-42ef-817e-3d70df86b6f1.conf with ostemplate
fedora-22-x86_64
Creation of Container private area failed
Failed to create the virtual machine.
- - - - -
It should also be noted that the fedora-22-x86_64.plain.ploopv2.tar.lz4 file I
crafted was huge ~750MB even using lz4's -9 compression level. I'm guessing it
was huge because the container's filesystem probably needed to be compacted but
I wasn't sure how to do that... but it doesn't matter because it didn't work
anyway.
I conclude that I probably got fairly close with the methodology BUT there are
factors I'm missing that I'm currently unaware of. :(
Anyway, the good news still is that I can "prlctl clone {ctid}" and then remove
the inherited IP address, set a new IP address... start the container... and
the new clone works. :)
TYL,
