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.

> Key: CLOUDSTACK-2354
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2354
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: ISO
> Affects Versions: 4.2.0
> Environment: Build No.#256
> (CloudStack-non-OSS-MASTER-256-rhel6.3.tar.gz)
> XenServer6.1 for Host Server, CentOS6.3 for NFS server and CloudStack-Mgr
> Server.
> Reporter: Minying Bao
> Assignee: Harikrishna Patnala
> Priority: Blocker
> Fix For: 4.2.0
>
> Attachments: ISO_Win8.jpg, ISO_XP-Auto-Shutdown.JPG.jpg,
> ISO_XP_State.JPG.jpg, management-server.log
>
>
> 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" )
