Removing further obsolete code from daemon-lib

Joshua Boniface 449f766a2c Lint: F821 undefined name 'zk_conn' 
Actually removes these entire sections of dead code; the daemon-common
library does no formatting at all since it is no longer used by the CLI.

Joshua Boniface ec0b8acf90 Support per-VM migration type selectors 
Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.

Joshua Boniface d42bb74dc9 Use explicit acquire/release instead of with 
The with blocks did not seem to work as expected. Go back to exclusive
locks as well since these are more consistent.

Joshua Boniface 3839040092 Add exclusive lock function 2020-10-21 10:46:41 -04:00
Joshua Boniface 84ade53fae Add locks for VM state changes 
Use exclusive locks during API events which change VM state. This is
fairly critical to avoid potential duplicate updates. Only implemented
for these specifically required functions to avoid major performance
hits elsewhere.

Joshua Boniface 72f47f216a Revert "Add locking in common zkhander" 
This reverts commit 53c0d2b4f6.

This resulted in a massive performance hit and some inconsistent
behaviour. Revert for now an re-investigate later.

Joshua Boniface 53c0d2b4f6 Add locking in common zkhander 
Ensures that every changed made here is locked, thus preventing
duplicate updates, etc.

Joshua Boniface e7ab1bfddd Add cluster overprovision determination 
Adds a check of (n-1) memory overprovisioning. (n-1) is considered to be
the configuration that excludes the "largest" node. The cluster will
report degraded when in this state.

Joshua Boniface f749633f7c Use provisioned memory for mem migration selector 
Use the new "provisioned" memory field, instead of the "allocated"
memory field, to determine the optimal node when using the "mem"
migration selector. This will take into account non-running VMs in the
calculation as well as running VMs.
 2020-10-18 14:17:15 -04:00
Joshua Boniface a4b80be5ed Add provisioned memory to node info 
Adds a separate field to the node memory, "provisioned", which totals
the amount of memory provisioned to all VMs on the node, regardless of
state, and in contrast to "allocated" which only counts running VMs.

Allows for the detection of potential overprovisioned states when
factoring in non-running VMs.

Includes the supporting code to get this data, since the original
implementation of VM memory selection was dependent on the VM being
running and getting this from libvirt. Now, if the VM is not active, it
gets this from the domain XML instead.

Joshua Boniface e4891831ce Better handle missing elements from net config 
Prevents situations with an un-editable, invalid config being stuck.
