Well, that's the<br>> average time it takes for me.<br>Since you are creating a server the default behaviour is to clone your<br>disks, which means engine calls copyImage to the SPM.<br>From what I saw in the logs your template have two disks, which one of<br>them is 1920 GB, this is why it took 30 minutes to copy it.<br></blockquote>It's 1920 GB but the actual data copied to it is only 1 GB. I'm used to other methods of saving virtual images (instead of sparse I mean) and as the original file is only 1 GB the copy doesn't last too much.<br><blockquote id="DWT377" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px; color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;">If you want your copy to be faster, you can change the default in the<br>resource allocation tab to use thin instead of clone when you add a new<br>server.<br>although, take in notice that when you will use thin provisioning, the<br>server will be based on the template and you will not be able to remove<br>the template until the VM will be removed.<br></blockquote>The thing is that if you select Clone (the default behaviour) then at the botton it says:<br><br>Alias | Virtual Size | Allocation | Target<br>First | 1920 GB | Thin Prov | local_storage<br>Seco | 1 GB | Preallocat | local_storage<br><br>so I thought:<br><br>If it lasts so much it means that someone it treats both hard disks as Preallocat no matter its particular disk allocation setup.<br>But as you say later in the email each one of it is treated ok.<br><br>So I think the problem is just the sparse method of saving the virtual images which makes read of big files to take an eternity even if a very few sectors are actually written.<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px; color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;">On 12/24/2012 01:51 AM, Adrian Gibanel wrote:> I've just noticed that I<br>made a typo.<br>> This is the right template disk allocation policy table<br>> (The fix is that second hard disk is preallocated instead of being<br>Thin Prov)<br>><br>> Alias | Virtual Size | Allocation | Target<br>> First | 1920 GB | Thin Prov | local_storage<br>> Seco | 1 GB | Preallocat | local_storage<br>I took a look in your logs, and it seems that when you create a VM from<br>template the passing arguments are preallocated for one image and sparse<br>for the other, so it seems that this is fit with the allocation policy<br>table you sent.<br></blockquote><br>I'm going to send a message about how to move virtual images between hosts.
