add iso partition to xenserver

link: https://adamscheller.com/systems-administration/xenserver-local-iso-storage-new-partition/

for posterity…

figure out the name of the volume group (something like name-uuid)

pvscan

 

create the new volume

lvcreate -L 150G -n ISOs name-uuid

 

find the volume you just created

 
lvscan |grep ISO

 

create the filesystem

mkfs.ext2 /dev/other-name-uuid/ISOs

 

make the mount point

mkdir /mnt/isos

 

create the repository

xe sr-create name-label=ISOs type=iso device-config:legacy_mode=true device-config:location=/mnt/isos content-type=iso

 

mount the disk

mount -t ext2 /dev/name-uuid/ISOs /mnt/isos

	


	







	

		
		
using vm-snapshot to clone a domU
	


	
	
	

		
CAUTION: with the following the system is up so you risk file loss, data loss, etc. — use at your own risk.


Ideally you would shutdown your domU and use vm-export rather than vm-snapshot.


make a snapshot


 xe vm-snapshot vm=name new-name-label=name-foo


this returns a uuid


  xe vm-export vm=UUID filename=|bzip2 > file.xva.bz2


move the file about


scp 192.168.1.2:file.xva.bz2 file.xva.bz2


import the snapshot


 cat file.xva.bz2 |ssh 192.168.1.1 "bunzip2|/opt/xensource/bin/xe vm-import filename=/dev/stdin"


then recreate the clone from the snapshot template under openxenmanager or other management tool.
