Add resource limits for virtual machines #7

Open ezwang opened 7 years ago

ezwang commented 7 years ago

Virtual machines currently have no resource limits, which may impact performance if a particular virtual machine is taking up too many resources. This could be implemented with Linux cgroups.

insert shameless kubernetes plug here

LXC has this functionality built in -- in the container configuration:

lxc.cgroup.memory.limit_in_bytes = 512M
lxc.cgroup.memory.memsw.limit_in_bytes = 1G

but I'm not sure if the conductor agent supports setting arbitrary config keys.

Is there a limit to the number of VMs that can be created? That should probably be added as well.
