Change in vdsm[master]: vdsm: add support for hot(un)plug of pci-passthrough devices

Martin Polednik has uploaded a new change for review. Change subject: vdsm: add support for hot(un)plug of pci-passthrough devices ...................................................................... vdsm: add support for hot(un)plug of pci-passthrough devices Hot(un)plug ability for pci-passthrough devices is extremely important in order to allow for hotunplugging/migrating/hotplugging workflow as VM cannot be migrated with pci device attached. This patch implements the ability adding new API verbs: hotplugHostdev and hotunplugHostdev, which attempts to append/remove the device from domain XML and reports back the state.

Change in vdsm[master]: vdsmcli: Add a contrib command line client alternative

For example: vdsmcli network is a command and 'show' and 'add' are its subcommands. Examples: toniel602 ~ # vdsmcli network show -k nics -k networks ============================================= Nics eth6 eth5 eth4 eth3 eth2 eth1 ============================================= Networks foo or toniel602 ~ # vdsmcli --verbode --pprint network show -k networks ============================================= Networks =============== foo =============== {'addr': '', 'bootproto4': 'none', 'bridged': False, 'gateway': '', 'iface': 'bond42', 'interface': 'bond42', 'ipv6addrs': ['2620:52:0:223c:201:a4ff:feac:8796/64', 'fe80::201:a4ff:feac:8796/64'], 'ipv6gateway': 'fe80:52:0:223c::3fe', 'mtu': '1500', 'netmask': ''} addition toniel602 ~ # ./cvdsm.py -v -p network add foo --bridgeless --nic eth4 --nic eth5 --bond bond42 Networks: {u'foo': {'bonding': u'bond42', 'bridged': False}} Bonds: {u'bond42': {'nics': (u'eth4', u'eth5')}} Succeeded.

Change in vdsm[master]: xen: do not attempt to read underlying device info
by Dan Kenigsberg 19 Oct '15

19 Oct '15

Dan Kenigsberg has uploaded a new change for review. Change subject: xen: do not attempt to read underlying device info ...................................................................... xen: do not attempt to read underlying device info Xen's device information is quite different than what Vdsm currently expects and needs. They lack bus address, alias, and driver. With this patch, Vdsm-on-Xen does not even attempt to read this information, which means that it would not be able to inract with the underlying devices. This is a hack which I do not expect getting into Vdsm proper. Much deeper refactoring is required to handle Xen devices.
