Joris van Lieshout created CLOUDSTACK-6023:
----------------------------------------------
Summary: Non windows instances are created on XenServer with a
vcpu-max above supported xenserver limits
Key: CLOUDSTACK-6023
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6023
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: XenServer
Affects Versions: 4.2.1
Reporter: Joris van Lieshout
Priority: Blocker
CitrixResourceBase.java contains a hardcoded value for vcpusmax for non windows
instances:
if (guestOsTypeName.toLowerCase().contains("windows")) {
vmr.VCPUsMax = (long) vmSpec.getCpus();
} else {
vmr.VCPUsMax = 32L;
}
For all currently available versions of XenServer the limit is 16vcpus:

http://support.citrix.com/servlet/KbServlet/download/32312-102-704653/CTX134789%20-%20XenServer%206.1.0_Configuration%20Limits.pdf
http://support.citrix.com/servlet/KbServlet/download/34966-102-706122/CTX137837_XenServer%206_2_0_Configuration%20Limits.pdf
In addition there seems to be a limit to the total amount of assigned vpcus on
a XenServer.
The impact of this bug is that xapi becomes unstable and keeps losing it's
master_connection because the POST to the /remote_db_access is bigger then it's
limit of 200K. This basically renders a pool slave unmanageable.
If you would look at the running instances using xentop you will see hosts
reporting with 32 vcpus
Below the relevant portion of the xensource.log that shows the effect of the
bug:
