How does one properly approach having Ubuntu servers on a Xen hypervisor? I don't have any experience with RAID or Xen other than from a theoretical level.
Additional requirements:
- Use with mdadm Software RAID 5 (can be on separate disks) that multiple instances with access
- Paravirtualized Ubuntu Server guests instances
Possible ideas for now:
- Ubuntu host (dom0) with ubuntu-xen-server package (this purportedly isn't supported)
- dom0 host will "own" RAID 5 partition
- More Ubuntu servers as guests
- Citrix XenServer bare-metal host
- XenServer will own RAID
- Citrix XenServer bare-metal host
- Ubuntu guest instance creates and owns RAID
Questions and concerns:
- Can Ubuntu be used as a dom0 Xen host?
- Can XenServer install packages such as mdadm and create a partition?
- Can multiple guest access (R + W) to the same data partition (RAID)?
Note: since it may have a bearing on support, I'm referring to Ubuntu Server 10.04
