Boot Hyper V and VirtualBox
- 
 Hello, I have problems to start FOG on clients from Hyper V and VirtualBox. The server assigns me IP but does not pass ipxe. What I can do? I enclose my dhcpd.conf file which I modified with the example that exists in the forum. PS: Sorry for my bad English. Thank you   
- 
 @mikmatcr From what you posted so far I can’t see what’s going wrong?! What do you get after the “iPXE initialising devices…” message on screen? 
- 
 @Sebastian-Roth The problem is that it does not advance of the message: iPXE initialising devices… It stays frozen, I have left it for several minutes and it does not display the FOG menu 
- 
 @mikmatcr Try changing line 57 of your dhcpd.conf file to filename "ipxe.pxe";and see if it makes a difference. Make sure you restart your DHCP service after the change.

 @Sebastian-Roth With that configuration, it worked for me. But now the problem is that the cloning speed is too slow, an average of 500MB / min. It can improve? Thanks for the iPXE tip

 @mikmatcr I can tell you both hyper-v and virtual box are really slow on image capture. I did some benchmark testing a few days ago because other mentioned really slow capture speeds which seem to be related to the legacy adapter in hyper-v that is needed to support pxe booting: https://forums.fogproject.org/topic/13396/unable-to-capture-windows-10-image/20

 @george1421 I was reading that using Gen 1 in Hyper v makes the legacy adapter very slow, but using Gen 2 should improve the speed, but if I create a Gen 2 virtual it displays an adapter error and SCSI Disk

 @mikmatcr First I’m not a hyper-v admin so my skills are not very good, but when I was testing I found that you can not boot from a scsi disk with hyper-v, you can only boot from ide. I was able to install centos on the scsi disk but it wouldn’t boot. I then researched and found that hyper-v is not designed for scsi booting. In my bench marking I did not attempt to test a Gen2 vm client.

 @mikmatcr OK since I still have the development system setup I just spun up a Gen2 vm client. MDT is currently building the golden image. I did see that they changed the disk controller to SCSI. It will take about 1hr for MDT to finish the build. I’ll get some bench mark numbers after that.
