-
XenServer Upgrades
- Do not have any suspended VMs
- Eject all CD drives of VMs
-
Pooled Setup & Linux Pack
- Hosts must have static IP
- Linux Pack must be on all hosts
- To later run Linux pack run script install.sh
-
XenCenter
- Can run multiple versions
- XenCentre 4.1 supports XenServer 4.0 hosts
-
NFS Storage setup
- chkconfig --list portmap
- chkconfig --list nfs
- chkconfig <service> on
- mkdir/<vm_share_dir>
- Edit the file /etc/exports and add
- /<vm_share_dir> *(rw,no_root_squash,sync)
- Save the file and close
service <service> restart
-
Create SR on NFS Share
- xe sr-create content-type=user type-nfs name-label=<sr_name=> \
- shared-true device-config-server=<server> \
- device-config-serverpath=<path>
- device-config-server: hostname of NFS server
- device-config-server-path: path on server
- Since shared=true, future hosts will be connected to this storage
-
Create SR on NFS Share
- xe pool-param-set uuid=<pool_uuid> \
- default-SR=storage_repository_uuid>
- xe pool-list: UUID of the pool
- Since shared=pool wiid default, future hosts will have disks created on this storage
-
Prepare iSCSI Storage
- Assign virtual storage volume on iSCSI SAN
- Create IQNs on SAN for each host (Use XenCenter or CLI)
- XenCenter used to create SRs for iSCSI or NetApp, contents of volume will be deleted
-
Configure iSCSI IQN via CLI
- Text Console: xe-set-iscsi-iqn <iscsi_iqn>
- CLI: xe host-param-set uuid=<host_uuid> other-config-iscsi-iqn=<iscsi_iqn>
- Repeat for each host
-
Create SR on iSCSI Share
- xe sr-create name-label=<name_for_sr>
- content-type=user device-config-target=<iscsi_server_ip_address>
- device-config-targetIQN=<iscsi_target_iqn>
- type-lvmoiscsi shared=true device-config-LUNid=<lun_id>
- Device-config-target: hostname/IP iSCSI server
- Device-config-LUNid: comma separated list of LUN IDs
