I'm not a fan of running anything that needs good performance on any kind of virtualization. At least you me really check that you get good IO performance out of it. Running Cyrus on x86_64 Linux seems to work well. At least I didn't get any problem report for a long time. I have not been a fan of x86_64 because of it's mixed 32/64bit arch but that's not really a problem these days. I was forced to migrate a server from RHEL3/i386 to RHEL5/x86_64 and it has just worked. Both were running my current RPMs and with the default database config used in the RPMs. I could just shutdown the old box, rsync -aH to the new box and start it up. However, you may search the archives because I think there can be problems with certain database backends (BDB) when doing the migration. The RPM should still take care of it because it converts all BDB to skiplist on shutdown to make things easy to migrate.
