Hi, What is cpu.overprovisioning.factor use for? Who can explain it more detailed? Thank you. -- Steven Liang Linux System Admin Phone: 1.416.499.8009 ext. 2865 Cell Phone: 1.647.718.5292 Email: stevenli...@yesup.com www.yesup.com | account.yesup.com

If you have 1G and a factor of 2, you van instantiate 2 machines with 1G. This is useful of you don't expect all machines top be running art the dame time.

Re: who can explain cpu.overprovisioning.factor more detailed?
Thank you for replying. I have another question. If there are only 8 core cpu on every hosts, can I assign 10 cpu to a vm?

I'm guessing here; I think you can but you'll get an error deploying it. On Wed, Sep 18, 2013 at 9:03 PM, Steven Liang wrote: > Thank you for replying. > I have another question.

Isn't it down to the MHz described in the service offering. Rather than core count?

Re: who can explain cpu.overprovisioning.factor more detailed?
I guess it would depend on the amount of CPU power you give, as and example if you give 10 cores with 1Ghz, the CS probably would allocate the VM if you have 8 real cores with 2Ghz each. 2013/9/18 Daan Hoogland > I'm guessing here; I think you can but you'll get an error deploying it. > > > On Wed, Sep 18, 2013 at 9:03 PM, Steven Liang wrote: > >> Thank you for replying. >> I have another question.

Re: who can explain cpu.overprovisioning.factor more detailed?
Compute Offerings in CloudStack are configured with both CPU speed (MHz) and CPU core count. CloudStack will not allow you deploy a VM using an offering with 10 cores if your hosts only have 8 cores, regardless of the configured CPU speed. The VM deployment will fail. Some hypervisors actually do allow such deployments, but the hypervisor vendors strongly discourage it. The documentation I've seen suggests there are performance problems with such a configuration. I've never seen a reason to use such a configuration and the best practices guides I've read recommend configuring VMs with the fewest cores possible. If anyone has a valid use case for this and really needs it, file an enhancement request to allow it in CloudStack.
