hypervkvpd: Fix a bug in IPV6 subnet enumeration
Last modified: 2013-11-20 23:52:23 EST
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).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I got the patch from upstream maintainer, but would rather wait couple of days
till it's accepted upstream.
Created attachment 772574 [details]
Can you please help us with how to test this issue? Thank you!
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.
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.
we QE have reproduced this bug with WS 2012 R2
host: Windows Server 2012 R2
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
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 .
