xen —
xen0 at pvbus?
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 # Update XenStore hostctl data/updated 1
xen driver first appeared in
OpenBSD 5.9.
xen driver was written by Mike
Belopuhov
<mikeb@openbsd.org>
from scratch, inspired by the FreeBSD implementation.
