I should have said the 4th, or 8 days... to complete the migration.

In terms of VPS security, Xen is likely to be safer than Virtuozzo.
 Tektonic uses Virtuozzo and Linode and Prgmr use Xen.  Also Virtuozzo
slices have no swap space.

Another thing I should have also mentioned is the Prgmr AUP, bulk mail is
not ok without special permission.  We run some lists and obtained approval.

I was going to try to show some memory stats of our slice at Tektonic...

Tektonic
# smem
smem requires a kernel >= 2.6.27

Prgmr, this is a small slice only running DNS.
