Joshua Boniface be20ba02a7 Handle VM states in flush more accurately
We don't want to block forever on a failure, so limit valid waiting
states to just those we know it should be in during a migration.

Joshua Boniface 20ae2186f9 Run VM state actions in a thread
Prevents blocking the main thread(s) while a VM is changing state. In
particular, this caused some issues with nodes not responding to
cancellation/reversal of a flush/ready state until the previous
migration was finished, which could cause issues. This entire subset of
actions is now threaded and so can run on its own in the background.

Joshua Boniface b17b7bf22b Add black magic to minimize ping losses
This particular arping interval/count, along with forcing it to run in
the foreground, seems to minimize the packet loss when the primary
coordinator transitions. Through extensive testing, this value results
in the, consistently, least amount of loss: 1-2 pings, at an 0.025s ping
interval, return "TTL exceeded", with no other loss, and only when the
node the test VM is on is the one switching to secondary state. No other
combination of values here, nor tweaks to other parts of the code, seem
able to reduce this further, therefore this is likely the best
configuration possible.

Joshua Boniface 8c252aeecc Implemented coordinated locked node transitions
The previous method was a "throw it in the sea"-type migration with some
(very arbitrary) sleep statements thrown in for good measure.
Reimplement this with some hard locking. During each phase of the
transition, the nodes acquire read/write shared locks to a Zookeeper key
so that they can tightly coordinate the actions of transferring each
part of the primary state between them. This is done in a subthread to
prevent strange blocking issues that were encountered, likely due to
business in the existing main thread.

Joshua Boniface 5995353597 Implement VM metadata and use it
Implements the storing of three VM metadata attributes:
1. Node limits - allows specifying a list of hosts on which the VM must
run. This limit influences the migration behaviour of VMs.
2. Per-VM node selectors - allows each VM to have its migration
autoselection method specified, to automatically allow different methods
per VM based on the administrator's preferences.
3. VM autorestart - allows a VM to be automatically restarted from a
stopped state, presumably due to a failure to find a target node (either
due to limits or otherwise) during a flush/fence recovery, on the next
node unflush/ready state of its home hypervisor. Useful mostly in
conjunction with limits to ensure that VMs which were shut down due to
there being no valid migration targets are started back up when their
node becomes ready again.

Includes the full client interaction with these metadata options,
including printing, as well as defining a new function to modify this
metadata. For the CLI it is set/modified either on `vm define` or via the
`vm meta` command. For the API it is set/modified either on a POST to
the `/vm` endpoint (during VM definition) or on POST to the `/vm/<vm>`
endpoint. For the API this replaces the previous reserved word for VM
creation from scratch as this will no longer be implemented in-daemon
(see #22).

Joshua Boniface 3b27a88128 Allow abort of shutdown state
Adds some logic to allow an active shutdown state to be aborted by
changing the VM to another state. Useful mostly if a VM is doing funky
things and not responding to the shutdown, but the administrator either
doesn't want to wait for the timer to expire (forcing an immediate
termination) or wishes to abort the shutdown attempt.

Joshua Boniface 8f160abf90 Handle cancelling flushes when new ones run
Store the flush_thread of a node as a class object. Before starting a
new flush thread (either flush or unflush), stop the existing one if it
exists to prevent further migrations, then start the new thread. Set the
object to None on init and again once the task actually finishes. Remove
the inflush flag as this is not required when using these threads and
functionally does nothing any longer, but add the flush_stopper flag to
trigger cancellation of the current job.

Joshua Boniface 7a8aee9fe7 Remove flush locking functionality
This just seemed like more trouble that it was worth. Flush locks were

flushing that were mostly fixed by the code refactoring, so this will
help test if those issues are truly gone. If not, will look into a
cleaner solution that doesn't result in unchangeable states.

Joshua Boniface 08cb16bfbc Revamp VM migration handling
This was very old code that was hard to follow and quite fragile, with
failures and infinite loops occurring fairly frequently. These changes
make the code more robust, including the addition of timeouts, some code
cleanup, and some improvements to the logical flow.

Also forces the libvirt migration to occur on the cluster network, which
couples to changes in the libvirtd listen (via pvc-ansible) and in
Daemon.py via the previous commit.

Joshua Boniface 85a5a8a0c9 Disable tx offloading on bridge interfaces
Reference: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717215#68

Without this, DHCP fails when traversing only the local bridge, for
Debian Jessie or earlier (and possibly other OSes as well), due to the
missing UDP checksums. This disables the offload and hence reenables
the checksums even on the software-only bridge.

Also rearranged the steps and added comments arround this section to
better clarify what each command is doing.

Joshua Boniface 464c69aac6 Only perform fencing duties on primary
There was really no need for this to be shared among all the

Joshua Boniface d4ebe63d9b Rename network device field
It seems much nicer and more consistent as "device" rather than as
"name".

Joshua Boniface 1d3f868206 Unify network devices and addresses in config
The old way of doing this was a little cumbersome, with an upper YAML
tree split between "devices" (name and MTU) and addresses. This commit
unifies these under the root "networking" section to make this section
clearer.

Joshua Boniface e70255dbd6 Support configurable interface MTUs
MTUs were hardcoded at 9000, which breaks if the underlying interface
or network switch does not support jumbo frames, a possible deployment
limitation. This has non-obvious consequences due to MTU mismatches
for certain services (Ceph, Zookeeper, etc.).

This commit adds support for configurable MTUs for each interface,
set in pvcd.yaml. The example has been updated to reflect this, with
a default of 1500 (the Ethernet standard).

This commit also adds autoconfiguration of the VNI device MTU based
on the `vni_mtu` value, the same for bridge networks and minus 50
(rather than 200 from the hardcoded value, based on the following
resource [1]) for VXLAN networks.

Joshua Boniface 14e9ba892c Wait on both sides for 30s
Still finding issues with the flush
2019-05-24 01:23:18 -04:00
Joshua Boniface ae37afcf75 Wait 10 seconds when starting pvc-flush
Without waiting the unflush will trigger too soon, before the
daemon is fully ready and such it fails in odd ways.

Joshua Boniface 4c5ce9b995 Perform additional tweaks to units
Use RemainAfterExit to avoid pvc-flush from auto-stopping immediately.

Use PartOf to tie services to the target itself.

Use --wait on flush to avoid daemon stopping before flush is complete.
