Sorry for posting again, but because the subject.Hi All,
I have 5 servers each:
Intel Quad Core i7 2.4Gig (8 processors)2 *1TB HDD2*1Gig NIC12G RAM
I installed XCP 0.5 on each and all are joining a resource pool.Then I installed
2 Centos 5.5 VM on each XCP host and I used the following command to specify the
number of vCPUs for each VM:
xe vm-param-set uuid=$VM_UUID VCPUs-max=4xe vm-param-set uuid=$VM_UUID
VCPUs-at-startup=4//I assigned 8 vCPUs on each host for VMs.
and for RAM size I used:
xe vm-param-set uuid=$VM_UUID memory-static-max=6xe vm-param-set uuid=$VM_UUID
memory-dynamic-max=6
I knew it is wrong and I have to leave at least 512M for the host.Am I correct?
Now all my VMs are halted but when I tried xentop I found CPU(%) high and some
times it reaches 100. So, is it normal? if not what is the best configuration
for 2 VMs on these hosts to get the best performance and use all resources?
Please can any one provide me the best configuration for 2 VMs on XCP host like
mine?
Sorry for my English !
Thanks in advance for any advice.
Inas
