Subject RE: max guest limit in hypervisor capabilities
Date Tue, 24 Jul 2012 13:03:14 GMT
I found that it is getting checked in the first fit allocator (server/src/com/cloud/agent/manager/allocator/impl/FirstFitAllocator.java).
The '==' check is incorrect though, should have been '>='. Please go ahead and file a bug
if this is not working as expected.

Code snippet

            //find number of guest VMs occupying capacity on this host.
            Long vmCount = _vmInstanceDao.countRunningByHostId(host.getId());
            Long maxGuestLimit = getHostMaxGuestLimit(host);
            if (vmCount.longValue() == maxGuestLimit.longValue()){
                if (s_logger.isDebugEnabled()) {
                    s_logger.debug("Host name: " + host.getName() + ", hostId: "+ host.getId()
+" already has max Running VMs(count includes system VMs), limit is: " + maxGuestLimit + "
, skipping this and trying other available hosts");
                }
                continue;
            }

As it is, limits of Xenserver default and xenserver 5.6 sp2 were already modified to 2 Not
like a UI related issue.
