Description Angelo Lisco 2016-02-29 08:22:01 UTC

Description of problem:
the e1000 driver included in the ipxe-bootimgs makes the interface freezes randomly during the download of the vmlinuz and initram files

Version-Release number of selected component (if applicable):
ipxe-bootimgs-20130517-8.gitc4bce43.el7_2.1.noarch.rpm

How reproducible:
To reproduce this bug, you have to have access on a VMware Vsphere environment

Steps to Reproduce:
1. Create a new vm on VMware Vsphere with an e1000 vNIC
2. Build an ipxe iso with static ip and configure it to download a kernel and and ram disk file in order to bootstrap the vm
3. Attach the iso and power-on the vm

Actual results:
Network interface freezes randomly during the download of the vmlinuz and initrd files

Expected results:
The vm boots without issues.

Additional info:
A patch to fix this bug was already submitted and included in the ipxe git repo on the 21/04/15:
https://git.ipxe.org/ipxe.git/commit/8958f62a1c85ff6b449a685a729b61b9ea69f50a

This patch is very important for the Satellite6/Foreman product because ipxe is used to simulate PXE-boot in case it is not available on the deployment network (and many enterprise company doesn't enable/have that).

Thanks for your attention

Verified. 

Introspected two VMware based VMs: one with a vmxnet3 nic the other with E1000 nic.  Out of 10 introspection cycles, both VMs completed introspection fine 10 out of 10 - 100% pass.
