I was trying to run multiple copies of ovs-vswitchd on different containers on the same host. But, I was not able start them in parallel because they all seem to try to grab all the available memory in the beginning, even I have specified --socket-mem parameter. Is there a work around for this?
If I started 2nd ovs-vswitchd after first one is up, release unneeded memory, then I was able to bring up both. Information on my environment: AnonHugePages: 161792 kB HugePages_Total: 8192 <-- that is 16 GB HugePages_Free: 7936 <--- each vswitchd used 128 pages HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB On my 2 core machines, I started vswitched with limit of 256MB --socket-mem 128,128 It appears that vswitchd look at that HugePages_Free parameter, grab all that free memory, then reduce to the limit specified in --socket-mem option John
