I currently have 2 x ESXi boxes that have VMs stored on a NFS/iSCSI debian lenny linux box. I had purchased a new whitebox server as an intended replacement for the linux box. I had always planned on installing opensolaris on the new hardware with this config;
2 x 640GB mirrored rpool 6 x 1TB in raidz2 This box was going to be built in parallel with the current server and I would have simply copied the VMDK files across. Main reason for the move to opensolaris is ZFS and all its goodness like; end-to-end checksumming expected good NFS and iSCSI performance (I'd be using b124 rather than 0906 due to poor iSCSI performance in comstar 0906) send/receive for backups snapshot cloning etc Now I'm having a change of heart and want to investigate the possibility of moving from three servers to two. Both of them opensolaris with xVM/zones as the virtualization tech. I'd like to build the two boxes spec'd thus; Intel i7 920 + 12GB 4 x 1TB SATA (raidz) xVM on b124 3 x 1000mb NICs (1 onboard, 2 added PCI-E) The plan is to have the VM files synced across to the 'secondary' node via ZFS send/receive so that should one fail I can simply restart the VMs on the second node. I may even be able to spread the VM load across the two nodes and sync each bunch of VMs to the 'other' node. My questions are; 1. Is xVM considered stable enough for use ? And in particular with ZFS underneath in dom0. 2. Can I run virtualbox on opensolaris dom0 ? 3. will the ZFS send/receive work as I intend ? 4. Should I just keep the central 'storage' server and continue with ESXi or Xenserver 5.5 ? Any thoughts or experiences would be great. -- This message posted from opensolaris.org _______________________________________________ xen-discuss mailing list xen-discuss@opensolaris.org
