Citrix snuffs Xen and NetScaler brands

XenServer always felt like one of their weaker products

At the same time, XenServer pushed VMware pretty hard for a free hypervisor, back in the day. They chucked in live migration between hosts, which everyone else wanted you to pay for, and you could remove snapshots without powering down the VM, which also kept it well clear of the bottom-end of the market.

The problem I had with it is that it nevery actually removed those snapshots. The disk image ended up as some ugly Logical Volume chain, and once you hit 255 snapshots the whole damn thing stopped. The VM would still run (slowly), but it wouldn't snapshot again.

And there are those who'd say "don't use snapshots for backups", but I had a very good system running based around Bacula, which did both file-level and VM-level backups. Wasn't the nicest for restoring, but it was cheap!
