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 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
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 .
