Hi @Junkhacker
It’s an raid array of 6x900gb 15k SAS drives connected to an HP P408i-a SR Gen10 Controller. All of it combined to a single drive in Windows.

@george1421 I tried the init_partclone.xz and set the parameter in tftp settings. The boot dialog specifies that it is using that file, but now the deploy process is even slower. Still with FOG 1.5.7 tho.

So if you introduce a physical machine to capture or deploy to what are your transfer rates? The physical machine doesn’t need to boot for this test, only to deploy the image to get the speed.

Unfortunately I cannot get a physical machine connected to the FOG server. It is installed in a datacenter and I cannot connect a PC to that DHCP server from where I’m at.

As for your VM is it a type 1 or type 2 (not the right words) hyper-v vm?

They are Generation 2. I might try a Generation 1…

Is the vm in uefi or bios mode?

UEFI. Generation 2 only uses UEFI. Generation 1 uses BIOS.

Also just for reference what OS is the hyper-v host running on?

It is running on Windows Server 2016

Did you install FOG using the git method or the tarball method?

It was installed with the Git method.

Read the entire thread so you can see how to install the inits without breaking your fog deployment: https://forums.fogproject.org/topic/13620/very-slow-cloning-speed-on-specific-model/12 Upgrading to 1.5.7.2 is not required to test these inits.

Okay! Thank you for your help. I will give it a try. There is nothing to break right now so I might just upgrade to 1.5.7.2 as well.

Thanks again!

Just had another try at it with the following results:

Capturing:

• Multiple Partition Image - Single Disk (Not Resizable)
• Partition - Everything
• Compression - 3
• PartClone Gzip
  Avg. speed 2.3GB/min, Image size 20GB

Deploying:

• Unicast
• Tried the lates Kernel - 5.1.16_mac-nvme-fix
• First partition (550mb NTFS) took 3 sec at 8GB/min
• PartClone froze at “Syncing…” after first partition for 4-5min
• PartClone goes on to second (FAT32) and third (RAW) partition with consistent speed 6-8Gb/min and does not freeze at “Syncing…”
• PartClone starts main partition at 6Gb/min and keeps that for 50 secounds before it starts slowing down and after 3min its down past 1Gb/min and now as I’m typing this 15minutes has passed and 15% of the process has been done and we are down to 355mb/min.

I am really baffled by this to be honest…

Thank you both for your replies!

@Junkhacker The purpose of this is to set up one VM as a Golden Config that get captured once the newest build of our software is installed and then deploy 10-12 VM’s for QA to test on.

@george1421 The FOG server is v1.5.7, installed fresh last week and I’ve been troubleshooting ever since. The FOG server is right now running with 48GB RAM and 8 vCPU just for error elimination and the clients I have tested with are configured with 4 vCPU and between 8-32GB RAM. They are all on the same virtual switch and the DHCP scope is on the host server.

Hi,

We have a setup where both the FOG Server and the machines we want to deploy are all virtual and on the same Hyper-V host, on the same hypervisor, and the deployment takes forever.

The speeds starts at 7Gb/min and steadily falls down into the low hundreds mb/min. Deploying one clean W10 machine of 15gb takes a couple of hours. Another thing I have noticed that I have not seen before when I have used this service on physical machines is that Partclone stays on Syncing for a couple of minutes between every partition.

Does anyone have experience with deploying virtual machines with FOG?
Are there any known problems or any Kernel that is preferred? Network between VM’s are +1Gbits measured with iperf3 and the NIC on the server is 2x1Gbits Multiplexor Adapter.

The host is brand new and has 2x AMD Epyc 7451 24core CPU, 320gb RAM and total disk area for storage of VM’s is 3.24GB

Happy for any suggestions!
Thanks in advance!
