Hi everyone , I have also been facing the same problem for the past few days. The max-mem parameter in the domU config file is completely ignored.Even if we specifiy maxmem parameter in the config file at boot time , boot time allocated memory is taken as the max memory possible for the domain.
Also i observed that the max vcpu parameter also behaves the same way.
VCPU Observations:
| 1]We can play around with only the no of VCPUs allotted at boot time or less.
|
|
Allocating max no of VCPUs dynamically is not reflected. i.e we can make max VCPUs of a domain from 5 to 10 dynamically BUT the 5 new ones are never used...they are always paused (possibly a bug in open source xen ?)
Is there a fix around these problems?
Thanks.....

I.e. show up with free -m on the >domU?
