# STEP 2. The initial memory allocation (in megabytes) for the new domain.
mem_size = 64


# STEP 3. A handy name for your new domain.
domain_name = "Test domain [%d]" % vmid


# STEP 4. Specify IP address(es), for the new domain.  You need to
# configure IP addrs within the domain just as you do normally.  This
# is just to let Xen know about them so it can route packets
# appropriately.

# STEP 5b. Set the VBD expertise level.  Most people should leave this
# on 0, at least to begin with - this script can detect most dangerous
# disk sharing between domains and with this set to zero it will only
# allow read only sharing.

vbd_expert = 0


# STEP 6. Build the command line for the new domain. Edit as req'd.
# You only need the ip= line if you're NFS booting or the root file system
# doesn't set it later e.g. in ifcfg-eth0 or via DHCP
# You can use 'extrabit' to set the runlevel and custom environment
# variables used by custom rc scripts (e.g. VMID=, usr= )
