I'm getting the following error trying to start a VM. I have 64 gb of RAM
on this host. I got this error once before and found that my swap partition
was only 2gb or so. I increased the swap size to 124GB and the problem went
away. Below is the error when trying to start a VM and below that is what
my output from "free -g". I don't see why I'm getting a swap file error
when there's plenty of it available.
- Cannot run VM. Host swap percentage is above the defined threshold.
- Check your configuration parameters for Host Swap Percentage.
- Cannot run VM. There is no host that satisfies current scheduling
constraints. See below for details:
- The host USARPAOVRTHOST02 did not satisfy internal filter Memory.

That's what I'm showing right now, but I don't have as many VM's running

yesterday when I got around the 15 vm mark.

Also, just to note, all of my VMs are configured for memory ballooning with
1.5gb guaranteed and can use up to 3gb. All VM guests are Windows 7 32bit.

iirc, you can either disable the swap check via the config
EnableSwapCheck, or change the threshold via
BlockMigrationOnSwapUsagePercentage
(which would be a confusing name if it affects RunVm and not only
migration...)

I'm concerned about disabling it and having unexpected behavior if the
system actually does end up using all of its swap space. Any insight?

change the percentage threshold then.
the idea is if you are swapping - its bad.
though, if you also have a lot of free memory, its kind of absurd to
block because there is a swap, but its not needed so it remains swapped.

Am I correct in understanding that vm's which aren't being actively used
are moved to swap space to free more available RAM? If so, that might be
what is causing my issue, since we usually have several VM's idle and not
in direct use.

Jeff,
I'd appreciate to get some more info on this;
First of all which ovirt version are you using?
Next, I'd appreciate if you can restore the no swap (swapoff)
and run on the host:
vdsClient -s 0 getVdsCaps
Then share the output with us.
Generally speaking swap is really bad for VMs, so we should be fine
without it. However when calculating the needed amount of memory we
reserve safety margins for various components such as vdsm itself.
We published the calculation here: http://www.ovirt.org/Sla/FreeMemoryCalculation
So feel free to add the numbers or share the data with us.
Thanks for the feedback,
Doron
