Subject [jira] [Commented] (CLOUDSTACK-2354) Unable to create Windows VMs using ISO
Date Thu, 23 May 2013 11:40:19 GMT


Stephen Turner commented on CLOUDSTACK-2354:

It is not supported to set dynamic_max < static_max before XenServer Tools (PV drivers)
are installed in the VM. The reason is that memory overcommit relies on the cooperation of
the VM to give back the memory it doesn't need.

If you haven't got tools and you reduce the dynamic values while the VM is running, it will
not hand back the memory and it will keep running at static_max. However, next time it boots,
it will only be given dynamic_max memory, while the VM OS will believe it has static_max available,
and this is likely to crash the VM.

The correct procedure is to install the tools first, and then reduce the dynamic values to
the range you want.

> Repro Steps
> Setup the cloudstack environment as normal. (Configured NFS & CS-Mgr Servers)
> Launch browser, start CloudStack WebConsole and finish to build a cloud step by step.
(It should use workaround of build#256 when building a cloud.)
> Register the ISOs to the CloudStack as follows Win7, Win8, 2k8R2, XP. Wait for "Status"
showing "Successfully Installed".
> Add instances from all above ISOs.
> Expected Result
> All the instances should be added successfully, and all the related VMs should be launched
successfully on XenServer Host.
> Actual Result
> Unable to create Windows VMs using ISO.
> VMs based on the Win8/Win7 ISOs -> WebConsole show "Error" (refer to screenshot "ISO_Win8.jpg")

> VMs based on the XP/W2k8r2 ISO -> WebConsole show "Running" -> Auto-shutdown during
the OS installation -> WebConsole show "Stopped" (refer to screenshots "ISO_XP-Auto-Shutdown.JPG"
and "ISO_XP_State.JPG" )
