I'm running vCenter Server 4.1u1 and ESXi 4.1u1 on our three hosts and I'm looking for a way to limit the number of concurrent vmotions to 2. In other words, if I select 10 VMs to vmotion from host A to host B I only want 2 vmotions to occur at the same time, then when the first two finish then two more start, etc. Any idea how to accomplish this?
here's a good article and the steps to increase/decrease
Thanks Troy. I had actually run into this article before and had tried setting: <maxCostPerHost>8</maxCostPerHost> which, according to the article, should have limited my number of warm VMotions to 2 but does not.
I'm running Windows 2008 R2 on the vCenter Server so the path for the vpdx.cfg file (Default location “C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter”) does not exist. However, I think that I located the correct file at: "C:\ProgramData\VMware\VMware VirtualCenter". Does this sound right?
Any other ideas?

Yes, that is the correct path.
Hummm, I'm wondering if this setting is no longer used in vSphere 4.1 as it seems to have no effect on the number of concurrent VMotions that I can perform (and yes, I have rebooted the vCenter Server after making the change).
Assuming that I followed the instructions in the above article correctly here is what the <vpxd> section of my vpxd.cfg looks like:
<vpxd>
<ResourceManager>
<maxCostPerHost>8</maxCostPerHost>
</ResourceManager>
<das>
<serializeadds>true</serializeadds>
<slotCpuMinMHz>256</slotCpuMinMHz>
<slotMemMinMB>0</slotMemMinMB>
</das>
<filterOverheadLimitIssues>true</filterOverheadLimitIssues>
</vpxd>
seems the math has changed a bit in 4.1. It is expained below. I guess you just need to a bit more to get to the number you are confortable with
i think these settings are used in 3.5 ...
i found one of the kb on vmotion in vsphere ..not very much relevent to this...but for your info..
Thanks ranjit99 for the article. That's exactly my issue; I don't want 4 concurrent VMotion operations as I want to limit it to 2. There must be a way somehow to limit this...
Does anyone else have any ideas?
