[one-users] suspend vm on esxi 5

Mon Apr 2 09:16:05 PDT 2012

Hi Tino,

I tried creating the image from esxi5, and then importing it into
opennebula, and finally the suspend/resume functionality started
working smoothly!

I anyway had to change a few things as opennebula wasn't accepting the
vm image I was getting from esxi 5.
In fact the vmware configuration in opennebula works when you have
vmname-s001.vmdk etc., but it doesn't when you have vmname-flat.vmdk.

By looking into the scripts I found that opennebula tries to find the
descriptor (the .vmdk renamed to disk.0), by looking at all the files
with vmdk ending, and omitting the ones that have the "-s00n" in the
name. I had to change that part so that it could omit also files
having "-flat" in the name.

Anyway now it is pretty slow as the vm it moves is around 16 GB. Is
there a way to speed it up?

thanks, best regards
carlo
