[ovirt-users] VDSM Memory consuption

[Daniel Helgenberger]

Hello,

in my LAB cluster I run into OOM conditions frequently because of a huge
VDSM process. The memory stats from my nodes right now:

Node A; running one VM:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 
 3465 vdsm       0 -20 18.6g 9.8g 8244 S 32.1 50.3  27265:21 vdsm                                                                                                                                                  
 7439 qemu      20   0 5641m 4.1g 4280 S 22.9 20.9  12737:08 qemu-kvm                                                                                                                                              
 2912 root      15  -5 2710m  35m 5968 S  0.0  0.2   0:04.76 supervdsmServer 

Node B, running 3 VMs including HosedEngine:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 
9079 vdsm       0 -20  9.9g 5.0g 7496 S 49.7 43.0  11858:06 vdsm                                                                                                                                                  
 3347 qemu      20   0 7749m 1.8g 5264 S  4.3 15.8   3:25.71 qemu-kvm                                                                                                                                              
18463 qemu      20   0 3865m 415m 5516 R  1.6  3.5 359:15.24 qemu-kvm                                                                                                                                              
11755 qemu      20   0 3873m 276m 5336 S 80.5  2.3  21639:39 qemu-kvm

Basically VDSM consumes more then all my VMs.

I thought of VDSM as a 'supervisor' process for qemu-kvm?

I attached recend vdsm logs as well as a screen shot.

Thanks!
