Fire up your large format printers!
The fine folks at X-Tech have put together an exhaustive (and large) poster showing all the existing and new cmdlets for managing XenServer through PowerShell.

I recently updated my lab machine to XenServer 6.0 and I wanted to create a local ISO repository on the DOM0 partition. I have 3 physical drives, one 250GB drive that holds the host partition and its backup and two 500GB drives that host VM’s. I know that only 8GB on the 250 GB drive are used for the host and its backup, so I wanted to create the local ISO repository in the remaining space.
Stop! Linux Time
Connect to the CLI of your XenServer.
fdisk –l shows my current partition tables
[root@MARLINSPIKE ~]# fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Dom0 contains 3 partitions. The first is where the XenServer host resides. The second is the host backup. The final partition is the rest of the unused space on the 250GB drive. In my file system, this is /dev/sdc3. The following commands will format and mount this space as an ISO partition.
[root@MARLINSPIKE ~]# mkfs.ext3 /dev/sdc3 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 29491200 inodes, 58952233 blocks 2947611 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=0 1800 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 32 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@MARLINSPIKE]# mkdir /mnt/iso/ [root@MARLINSPIKE]# mount -t ext3 /dev/sdc3 /mnt/iso/ [root@MARLINSPIKE]# echo "/dev/sdc3 /mnt/iso ext3 defaults 1 1" >> /etc/fstab [root@MARLINSPIKE]# xe-mount-iso-sr /mnt/iso -o bind
Now the new ISO partition shows up in my XenCenter console.
