<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">Hello,</span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;"></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">the problem is "waiting for launch" takes up to 20 min.</span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;"></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">I did a lot of tests with some vm's and th problem is:</span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;"></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">1. create a win2012 server</span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">2. attache a new disk (thin provision)<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">3. fill the disk from network share with about 100G<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">4. shutdown the vm<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">5. reboot host and try starting the vm (takes a lot of time until launch)<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">It's because of a high fragmented filessystem <br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 12pt; font-family: tahoma,arial,helvetica,sans-serif;">Thanks<br /></span></p>

If a VM doesn't start at all then there should be some ERROR<br />message in the log. If all the VMs eventually start sooner or later,<br />then it would be useful to see the whole piece of the log from the<br />initial VM.create call to the VM start.<br /><br />And what do you mean exactly by the VM start? Is it that a VM is not<br />booting in the meantime, is inaccessible, is indicated as starting or<br />not running in Engine, something else?<br /></pre>
