Subject [jira] [Commented] (CLOUDSTACK-2354) Unable to create Windows VMs using ISO
Date Fri, 24 May 2013 09:36:20 GMT


Nitin Mehta commented on CLOUDSTACK-2354:

Thanks Stephen. Based on your comment I am assuming that atleast the windows ISOs we will
never be able to deterministically find out when the PV drivers got installed. The reason
is when we stop the vm from Cloudstack it actually destroys it on the XS and when you are
deploying the vm you cant beforehand know whether the template/ISO has the PV drivers correct
? In fact this is true for any template that do not come with PV drivers correct ? We will
now have to rely on the user to signal to us explicitly that he has installed PV drivers than
finding out ourselves.

Also I had one observation to share that while deploying a windows template even though the
dynamic_max < static_max it deployed fine for me. Any idea how ?
Another question is whether dynamic_max < static_max the only issue if PV drivers do no
exist ? Can we deploy a vm with a setting like static_min = dynamic_min = X < dynamic_max
= static_max = Memory_overprovisioning_factor * X ? This would be useful for memory overprovisioning.
Is this documented somewhere that for DMC to work we need PV drivers and some related readings
so that I am more informed on this ?

Thanks again for your prompt help

>    Affects Versions: 4.2.0
>         Environment: Build No.#256 (CloudStack-non-OSS-MASTER-256-rhel6.3.tar.gz)

>         Attachments: ISO_Win8.jpg, ISO_XP-Auto-Shutdown.JPG.jpg, ISO_XP_State.JPG.jpg,
> 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" )
