I've gotten reasonably comfortable with manual instantiation of vserver guests, and would like to start manipulating them by scripts.
A few questions for my basic understanding: 1) if I vserver vXY stop, can I package the static directory with tar and copy it somewhere/rsync it someplace else, will the entire state will be saved? Including e.g. PostgreSQL dbases, or will I have to make a dump and reimport afterwards? Which files context is still missing (which directories would I also have to rsync?) 2) Are there any demo scripts which instantiate a fully-formed/preconfigured e.g. Debian host with a given IP address? Add users or packages after the fact (or is it easier to execute scripts as root in a running guest?) Pointers to list archive are very fine. 3) Are there any existing scripts to migrate a running guest to a different server? A simple way would be to do a variation of question 1). Can I make vserver guests live on a NFS partition? Lustre? PVFS? Is there a way of keeping two running guest instances synchronous, save of a HA/drbd based setup? (I have some very basic understanding of it, just enough for a HA NFS system). I realize some snapshot/migration functionality for clusters is being worked on -- how far is this removed from production? 4) Is there a simple way to limit host file system size to a fixed limit, e.g. multiple of 1 GByte? I would like to start working with an amd64-debian based machine (only 4 GBytes, though -- should I then just stick with vanilla 32 bit Debian, or does this result in a noticeable performance hit on 146 Opterons?), so if anyone has a working vserver-patched amd64 kernel package I would very much like a copy (Markus, are you there?). -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
