Description Tomáš Hozza 2013-07-12 06:15:51 UTC
Description of problem:
I got an email from upstream maintainer:


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.

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 .
