Unable to MIgrate VDI when host is low on free memory
-
I have a small server that I use as a test host, and I added some SRs on it that are network-based. One is NFS and the other is iSCSI. VMs work fine on these SRs, but when I go to migrate a VDI on a running VM, with the Xen tools, I get a "not enough free RAM" error regardless of whether I try to migrate it to the NFS or iSCSI SRs. This host is very short on RAM. I am running the latest patched 8.3 with QCOW enabled. I tried two machines. One was an existing with a VHD disk and the other is a VM with a QCOW2 disk.
Thank you for the help.

Hi,
Low how? can you provide some numbers? Thanks!

@olivierlambert Here is the amount of free RAM on the system.
But when I try to migrate a VDI to a new storage repo, I get this error:
HOST_NOT_ENOUGH_FREE_MEMORY(8663334912, 3104964608)
I can create a new VM on that SR without issue.

Do you have dynamic memory set for your VM?

You say you're trying to migrate a vdi, where are you trying to migrate it?
To a SR attached to your current host or to another host/pool?If you're trying to migrate it to another host/pool this is something that i've seen as well when dom0 is not assigned enough RAM, we usually gave them 16Gg which seemed to resolved these kind of issues back when we were running 8.2.0.
