vmkernel log entries match with VM name?

[mlubinski]

Hi,

Below you can see what I see sometimes in /var/log/vmkernel log.

Dec 18 05:12:21 esx001 vmkernel: 14:12:53:59.793 cpu5:1521)WARNING: Swap: vm 1521: 7515: Swap sync read failed: status=195887167, retrying...

In this example I know that these 2 VMs: 1521 and 1302 had problem in the morning, and they will probably crash or crashed already.

How can I check which ones are they?

When I do vm-support -x, I get a list of VMs, and on this list there are:

vmid=1302 vm001

vmid=1521 vm009

but are they really these from the log?

Yes, these are indeed the same... Stats from these VMs can also be seen in the processes in the /proc/vmware/vm/ dir.. ...

Ok, and what if after such log entry one of these vm's will be vmotioned to different host? How to trace this one after such move?

Get the vmid from the vm-support -x output on the targeted host after movement... Then grep for this id in the logs..

Ok,so it means that vmid will not change after vmotion? And what after

reboot?will vmid change?

Thx for your reply:)

The vmid does change...

That's why you need to check the id on the host targeted after vMotion..
