Hi, I changed Xen_Start/Xen_Stop functions in the Xen OCF resource script. The Xen_start now makes a xm mem-set to already running machines, to shrink the memory of these to make sure the new domain will be able to start. In Xen_stop I did sth. similar. xm mem-set is called, after the domain is stpped, to raise the memory for the remaining virtual domains. So far, after some tests, this works well.
Now the hard part is live migration. On live migration, the virtual node is not stopped when transferred between two nodes. This work well as long as on the destination host is enough free memory available. Is there a possibility on the source host to figure out how many memory is available on the destination host? Or any other idea? kind regards Sebastian _______________________________________________________ Linux-HA-Dev: [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/
