Commandes principales
Les fichiers d'images sont dans /home/xen/domains
pour démarrer un serveur :
# xm create nom_du_serveur.cfg
pour le reste :
# xm
vous donnera les autres commandes dispos
Augmenter la taille d'un serveur :
first create an extra image with the desired size (here 1GB) that will be added to the current image
# dd if=/dev/zero of=extra.img bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 5.09034 seconds, 211 MB/s
Make sure domU is not running. Then just add extra.img to your domU image file (here domU.img). Yes just as simple Very Happy
# cat domU.img extra.img > domU.resize.img
You also need to enlarge your filesystem. I've test it with ext3 but not with ReiserFS - it seems ReiserFS needs resize_reiserfs instead of resize2fs -.
# fsck.ext3 -f disk_resize.img # resize2fs domU.resize.img
Finally modify your domU config file or move domU.resize.img over domU.img.
