Overview
xen driver performs HVM domU guest initialization, provides abstraction for virtual Xen interrupts, access to the XenStore configuration storage as well as a device probing facility for paravirtualized devices such as disk and network interfaces.
When running under XenServer, to let the host know that the guest has finished initializing and to allow graceful shutdown, set the following XenStore properties with hostctl(8) in rc.local(8):
ostype=$(sysctl -n kern.ostype) osrelease=$(sysctl -n kern.osrelease) # XenServer Tools version hostctl attr/PVAddons/MajorVersion 6 hostctl attr/PVAddons/MinorVersion 2 hostctl attr/PVAddons/MicroVersion 0 hostctl attr/PVAddons/BuildVersion 76888 hostctl attr/PVAddons/Installed 1 # OS version hostctl data/os_name "$ostype $osrelease" hostctl data/os_uname $osrelease hostctl data/os_distro $ostype # Inform Xen of IPs bound to the VM hostctl attr/vif/0/ipv4/0 192.0.2.1 hostctl attr/vif/0/ipv6/0 2001:db8::1 # Update XenStore hostctl data/updated 1
