Re: [Openstack] [Nova] CPU Scalling, Quota for Disk I/O

2013-07-10 Thread Yaguang Tang 
Here is a wiki  about this feature,
https://wiki.openstack.org/wiki/InstanceResourceQuota
you can set CPU, disk IO consume policy, network traffic bandwidth for
specified flavor. so the instance of that flavor can only consume under
controlled physical resource.

Re: [Openstack] nova-compute cannot restart when vmware vcenter confguration.

2013-05-19 Thread Yaguang Tang 
can you put more nova-compute log info? also there is a known bug that may
cause nova-compute can't starts, it's fixed in nova stable/grizzly
(2013.1.1) which may not in ubuntu deb repo, if this is the case, you need
to patch manually or wait for ubuntu official update to 2013.1.1. the patch
is
https://github.com/openstack/nova/commit/b2ec66823baf2a5094a9b398c2554bdcd2aba928
.

hope it helps.
