Subject [jira] [Created] (CLOUDSTACK-904) CloudStack export the CPU as a socket not core
Date Tue, 08 Jan 2013 21:48:13 GMT
Ahmad Saif created CLOUDSTACK-904:

             Summary: CloudStack export the CPU as a socket not core
                 Key: CLOUDSTACK-904
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM
    Affects Versions: 4.0.0, pre-4.0.0
            Reporter: Ahmad Saif
            Priority: Minor

I've a VM that's running (Windows 2008 Standard R2 64bit) which was working on a 4 cores offer.
when I upgraded the service offer to 8 cores and checked the VM I noticed that it still have
only 4 cores !!

I dig a little bit on the windows machine itself, and found that it see the CPUs as sockets
not cores and this version of windows support only up to 4 cores.

when I checked the vm XML file on the host I saw that the CPU is exported as following :


and it should be exported as following:

<vcpu>1</vcpu> <cpu>
<topology sockets='1' cores='8' threads='1'/>

otherwise in such systems where you are limited with the sockets number you cannot have the
required service offer.
