Description of problem:
I got an email from upstream maintainer:

Thomas,

Please pickup this patch for both RHEL 6.4 and RHEL 6.5. Without
this patch IP GET functionality will not work on ws2012 R2 (Windows Blue).

Thank you,

I got the patch from upstream maintainer, but would rather wait couple of days
till it's accepted upstream.

Comment 4 RHEL Product and Program Management 2013-07-12 10:50:06 UTC
This request was evaluated by Red Hat Product Management for
inclusion in a Red Hat Enterprise Linux release.  Product
Management has requested further review of this request by
Red Hat Engineering, for potential inclusion in a Red Hat
Enterprise Linux release for currently deployed products.
This request is not yet committed for inclusion in a release.

Comment 5 K. Y. Srinivasan 2013-07-12 11:34:38 UTC
The bug was exposed when testing on the about to be released ws2012 r2. The following command executed from a power shell window (opened with admin rights):

Get-VMNetworkAdapter -VMName name_of_the_vm

You will see that without this patch, the IP addresses will not be listed. I am assuming here that you have already picked up the kernel vmbus patch that correctly negotiates the protocol version.

Comment 6 lijing 2013-07-15 10:47:38 UTC
we QE have reproduced this bug with WS 2012 R2

version info:
host: Windows Server 2012 R2
guest: RHEL6.4(2.6.32-358.el6.x86_64)
hypervkvpd: hypervkvpd-0-0.9.el6

the step as below:

1. install RHEL6.4 guest
2. check the hypervkvpd status
#service hypervkvpd status
3.Check that the SELinux is enabled on the guest
4. run the command below on host
#Get-VMNetworkAdapter -VMName name_of_the_vm |ft ipaddresses

Comment 9 lijing 2013-09-13 07:46:56 UTC
verify this bug , install RHEL6.5 x86_64 and i386 guest on WS 2012 R2, the kernel of which is 2.6.32-415.0.1.el6.x86_64/2.6.32-415.0.1.el6.i686 with hypervkvpd-0-0.12.el6.x86_64/hypervkvpd-0-0.12.el6.686 , get correct IP information from guest .
