Resetting Xen Server Networking from Xen Hypervisor

Posted on by

From my colleague Jan.

DOM=$(xe vm-list name-label=instance-2fgfgf763fgfgidsfiusdf783hj params=dom-id –minimal)
UUID=$(uuidgen)

# Verify Variables set correctly
echo Domain: $DOM UUID: $UUID

# Perform resetnetwork
xenstore-write /local/domain/$DOM/data/host/$UUID ‘{“name”:”resetnetwork”,”value”:””}’

# wait few seconds
xenstore-read /local/domain/$DOM/data/guest/$UUID

# if that is problematic then check if request is hanging:
xenstore-ls /local/domain/$DOM/data
