I understand that Rackspace is rebooting physical servers. They also have the knowledge to know what VM's are running on said machines, and they also have the ability to migrate the VM's from one compute node to another compute node.
- harlowja 12y agoIf they have network block storage you would likely be correct, but afaik they also give you emphemeral storage that is local to the hypervisor which is not network block storage and therefore makes it very very hard and very very slow to migrate you around automatically (ever tried transferring a 20GB+ file around, ya, it takes forever...)

- regularfry 12y agoDepending on the nature of the patch, they might not be able to migrate from unpatched to patched hosts. KVM upgrades can also be fun that way.
