aea47dd6a0 fix #1471: change keyboard default to undef
this means that we do not include the '-k' parameter anymore by default
(which is deprecated by qemu)

with this, noVNC and spice always respect the guest keyboard
configuration and altgr keys work without problems

tested:
ubuntu with english intl and german with novnc and spice
windows 10 with english intl and german with novnc and spice
live migration

5e67a2d2c4 check if base volumes are unused before deleting a template

at which point we do not stop to delete the vm even when a
disk deletion fails, which means we could successfully delete the config
and all not used (base) disks of a template, resulting in left over vm disks

Also the disk was created with a specific format and then a format

We cannot look for ports on "any" wildcard address while
letting qemu bind to "localhost", this may lead to a qemu
process occupying ::1 while the next search successfully
finds the same port available for IPv4's '*' address.

Instead, we now lookup the IP of the desired family for
'localhost'. Note that while we could simply be hardcoding
::1 or 127.0.0.1, with this code we are protocol agnostic.

2de2d6f74e allow dedicated migration network, bug #1177
Without this patch we use the network were the cluster traffic runs
for sending migration traffic. This is not ideal as it may hinder
cluster traffic. Further some users have a powerful network which
would be perfect for migrations, with this patch they can run the
migration traffic over such a network without having the corosync
traffic on the same network.

The network is configurable through /etc/pve/datacenter.cfg which
got a new property, namely migration. migration has two
subproperties: type (replaces the old migration_unsecure property)
and network.

For the case of a network failure or that a VM has to be moved over
another network for arbitrary other reasons I added the
migration_type and migration_network parameters to qm migrate (and
respectively vm_start as this gets used on migration).
They allow overwriting the datacenter.cfg settings.

when restoring into an existing VM, we don't want to die
half-way through because we can't delete one of the existing
volumes. instead, warn about the deletion failure, but
continue anyway. the not deleted disk is then added as
unused automatically.

drive-mirror is not working with qemu 2.6 when iothread is enabled.

ec647db4f8 Fix #1057: make protection a fast-plug option
Otherwise you need to shutdown a VM to disable protection,
which is inconvenient for a few tasks such as for instance
deleting an unused disk.

f745762b2e disable usb hotplug for now
we have a few problems with hotplug at the moment:
qemu may add usb hubs when adding usb devices but fails to remove them
when removing the usb device (this is a qemu bug)

also when starting a guest with a usb device we add ehci and uchi
controllers, which we cannot hot unplug

with those devices, it is impossible to live migrate the guest
to another host, meaning even if you remove all usb devices,
the migrate fails

so we deactivate usb hotplugging for now

7023f3ea16 add hugepages option
vm configuration
----------------
hugepages: (any|2|1024)

any: we'll try to allocate 1GB hugepage if possible, if not we use 2MB hugepage
2: we want to use 2MB hugepage
1024: we want to use 1GB hugepage. (memory need to be multiple of 1GB in this case)

optionnal host configuration for 1GB hugepages
----------------------------------------------
1GB hugepages can be allocated at boot if user want it.
hugepages need to be contiguous, so sometime it's not possible to reserve them on the fly

/etc/default/grub : GRUB_CMDLINE_LINUX_DEFAULT="quiet hugepagesz=1G hugepages=x"
