Fixed In Version:	qemu-kvm-0.12.1.2-2.306.el6	Doc Type:	Bug Fix
Doc Text:	Cause: E1000 emulation loads the field of POPTS for every descriptors of a multi-descriptors buffer, this conflicts with the spec which requires that the field is ignored excepted on the first data descriptor of a packet. Consequence: E1000 does not work well when it tries to use multi-descriptor for a packet. Fix: Check this field onyl for the first descriptor. Result: E1000 works well for solaris guest.

Description Joaquin 2012-05-08 15:38:56 UTC

Description of problem:
qemu emulation of e1000 nic does not follow the specification

Version-Release number of selected component (if applicable):
qemu versions below 0.15.1


How reproducible:
Start a virtual machine with some OS that has no virtio and does not work with the old e1000-emulator. 

At least all SunOS 5.10 or OpenSolaris and Illumos based systems like Solaris 10, Nexenta, SmartOS, Illumian, ...  are affected.


Steps to Reproduce:
1. create a virtual machine with e1000 NIC in a network with a DHCP-server
2. let it run the OpenIndiana live DVD
http://dlc-int.openindiana.org/repos/
Latest ISO at this moment is
oi_151a_prestable2_repo.tar.bz2
3. wait until the Gnome desktop is shown

or use any other affected OS and try to use the network
  
Actual results:
See that when the Gnome desktop is shown the system does not get a DHCP lease, the Network Manager icon remains orange
(sending out packets works, return packets are not received). 
(sudo) password when selecting the Network Manager is "openindiana"



Expected results:
The system will get a DHCP lease and the network is functional (i.e. in the Gnome desktop the network icon will turn green)

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 5 RHEL Program Management 2012-07-11 02:07:06 UTC

This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
