Joshua Boniface 8c4c1aba38 Revert "Add object-map to default RBD volume features" 
This reverts commit 00e9cca6f0.

This causes RBD mapping to fail on Debian 10. Reverting but keeping in
history for future reference.
 2021-02-28 01:57:30 -05:00
Joshua Boniface 00e9cca6f0 Add object-map to default RBD volume features 
This allows for much quicker image deletes especially for empty images.

Joshua Boniface ab05e0f3db Add B suffix back to bare bytes values 2021-02-17 11:37:36 -05:00
Joshua Boniface 9291ce6ffc Correct output of fromhuman and add size compare 
Ensures that the bytes_tohuman returns an integer to avoid the hacky
workaround of stripping off the B.

Adds a verification on the size of a new volume, that it is not larger
than the free space of the pool to prevent errors/excessively-large
volumes from being created.

Closes #120

Joshua Boniface 1b6613c280 Add live VNC information to domain output

VMs.

Closes #115
 2020-12-20 16:00:55 -05:00
Joshua Boniface f58e95e4c1 Fix bugs in modifying networks 
1. Use a consistent "is not None" to verify records are changing.
2. Fix bug where IPv6 network had no remove setter (it is now a blank
string, the first thing I would expect).
3. 1 fixes a bug whereby it was impossible to unset DHCPv4 status.

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.
 2020-10-21 10:40:00 -04:00
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.
 2020-10-21 03:49:13 -04:00
Joshua Boniface 53c0d2b4f6 Add locking in common zkhander 
Ensures that every changed made here is locked, thus preventing
duplicate updates, etc.
 2020-10-21 03:17:18 -04:00
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.
 2020-10-18 14:57:22 -04:00
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.

Prevents KeyErrors and such.
 2020-08-21 10:10:13 -04:00
Joshua Boniface 15e78aa9f0 Add status information in cluster status 
Provide textual explanations for the degraded status, including
specific node/VM/OSD issues as well as detailed Ceph health. "Single
pane of glass" mentality.
 2020-08-17 12:25:23 -04:00
Joshua Boniface 2b4d980685 Display Ceph health in PVC status as well 
Makes this output a little more realistic and allows proper monitoring
of the Ceph cluster status (separate from the PVC status which is
tracking only OSD up/in state).

Joshua Boniface 0468eeb531 Support live resizing of running disk volumes 
This wasn't happening automatically, nor does it happen with qemu-img
commands, so we have to manually trigger a libvirt blockResize against
the volume. This setup is a little roundabout but seems to work fine.

Joshua Boniface ce60836c34 Allow enforcement of live migration 
Provides a CLI and API argument to force live migration, which triggers
a new VM state "migrate-live". The node daemon VMInstance during migrate
will read this flag from the state and, if enforced, will not trigger a
shutdown migration.

Closes #95

Joshua Boniface 07577a52a9 Implement wait support for various VM commands 
Implements wait support for VM restart, shutdown, move, migrate, and
unmigrate commands, similar to node flush/node unflush.

Includes some additional refactoring of the move command to make its
operation identical to migrate, only without recording the previous
node.
