I've come across what is seemingly a hard cap for the amount of concurrent VMs I can run on a Linux based machine (after posting on the support forums, I was directed here). Apparently this same cap was encountered on a solaris host and a fix was deployed to increase the amount of VMs that were allowed to run at the same time. Was this fix supposed to be included in other OS releases? Any information on this would be greatly appreciated.
That's a rather vague statement, and if you could tell what number of concurrently running VMs you can achieve I might be able to infer what limit is causing trouble for you.
It could be the SysV semaphore count, the number of open files per process, and so on. All these defaults depend on the kernel configuration and/or distribution, so it's hard to generalize.
Solaris is easy compared to that, as it is very uniform compared to Linux. Klaus
