Hi This is my first post on this forum so please, if I don’t follow the guidelines as wanted… Let me know! side-note: My Linux experience is rather outdated since the last couple of years I worked mainly on M$ OS’s. The issue. I need hyper-v modules: A client I am working for had this server (SLES 11 SP3 kernel 3.0.101-0.47.52-default) setup in a VMware environment. They now are migrating to Hyper-V on W2k12 R2. For as far my knowledge reaches I cannot find the LIS hyper-v modules. Can anyone point me in the direction where: - I should find these module in the OS (searched /etc/init.d/ but nothing there) - If these are not installed, where I could find these modules? Also checked in Yast but nothing comes out. FYI: Already adjusted the kernel since I was in the assumption that they would be installed and just needed to load but that does not seems to be the case. I am following these steps for getting SLES running on Hyper-V; [https://technet.microsoft.com/en-us/library/dn873998.aspx](https://technet.microsoft.com/en-us/library/dn873998.aspx) Kind regards and thanks in advance for helping me out.

Hi HB, looking at some SLES11SP3 server here, I do see the Hyper-V tools RPM, which is probably what you’re looking for: [CODE] [FONT=monospace][COLOR=#ff5454]~ # [/COLOR][COLOR=#000000]zypper se hyper-v [/COLOR] Refreshing service ‘SMT-http\_cool\_server\_over\_here’. Loading repository data… Reading installed packages… S | Name | Summary | Type –±----------------±-------------------------------±---------- | hyper-v | Microsoft Hyper-V tools | package | hyper-v | Microsoft Hyper-V tools | srcpackage | slessp3-hyper-v | Recommended update for hyper-v | patch [COLOR=#ff5454]~ # [/COLOR][/FONT][/CODE] Regards, Jens ---

Indeed, that was what I was looking for. Thanks for the tip! I’m running the kernel rebuild now… I guess I should see the modules via lsmod in this package after rebooting the server? (hv\_vmbus, hv\_netsvc, etc.) kind regards HB ---

Hi HB, > I’m running the kernel rebuild now… usually, you do not recompile on a SLES production server… Further digging into the subject, I had a look at the contents of the Hyper-V RPM: [CODE] [FONT=monospace][COLOR=#ff5454]#[/COLOR][COLOR=#000000] rpm -ql -p SLES11-SP3-Updates/sle-11-x86\_64/rpm/x86\_64/hyper-v-5-0.11.1.x86\_64.rpm [/COLOR] /etc/init.d/hv\_kvp\_daemon /etc/init.d/hv\_vss\_daemon /usr/lib/hyper-v /usr/lib/hyper-v/bin /usr/lib/hyper-v/bin/hv\_get\_dhcp\_info /usr/lib/hyper-v/bin/hv\_get\_dns\_info /usr/lib/hyper-v/bin/hv\_set\_ifconfig /usr/sbin/hv\_kvp\_daemon /usr/sbin/hv\_vss\_daemon /usr/sbin/rchv\_kvp\_daemon /usr/sbin/rchv\_vss\_daemon /usr/share/doc/packages/hyper-v /usr/share/doc/packages/hyper-v/kvptest.ps1.txt # [/CODE] [/FONT] So there’s nothing in terms of kernel modules in that package, but rather daemons. Have you tried looking at the doc file and/or starting the daemons? Probably, the required modules are already part of the distributed kernel. If manually starting the daemons helps, you can configure their autostart via “chkconfig [FONT=monospace]hv\_kvp\_daemon on; chkconfig [/FONT][FONT=monospace]hv\_vss\_daemon on”[/FONT] Regards, Jens ---

Hi First off… Apologies for the confusion and thanks for your help! To be honest, I do not know I need these Hyper-V tools to get this server to boot after migrating to Hyper-V anyway. I just wanted to make sure I had everything installed on the SUSE guest, guess these tools are for interaction between the host and guest (kinda like vmware-tools). After some digging I did find the modules I was looking for on the system, at least, I can lookup the information regarding these modules via modinfo hv\_vmbus, the only one that is not on the system is hv\_blkvsc. I did do the rebuild because I added these modules to the kernel(bold). Guess they are not initially submitted in the kernel because there was no need since the server is setup on VMWare. [I]INITRD\_MODULES="mptspi ata\_piix ata\_generic vmxnet3 vmw\_pvscsi vmxnet hv\_vmbus hv\_netvsc hv\_storvsc hv\_blkvsc” resource: [https://technet.microsoft.com/en-us/library/dn873998.aspx](https://technet.microsoft.com/en-us/library/dn873998.aspx) SUSE Linux Enterprise Server 11 (SP2 and SP3) require additional steps to enable Linux Integration Services when migrating from VMware to Hyper-V. Perform these steps on the SUSE Linux Enterprise Server 11 SP2 or SUSE Linux Enterprise Server 11 SP3 virtual machine before conversion: Edit /etc/sysconfig/kernel to include the Hyper-V LIS modules. Add the hv\_ modules to the INITRD\_MODULES line. It should look similar to this: INITRD\_MODULES="mptspi ata\_piix ata\_generic vmxnet3 vmw\_pvscsi vmxnet hv\_vmbus hv\_netvsc hv\_storvsc hv\_blkvsc” Re-create the initrd with the following command. The kernel specified in the command must match the current kernel that the virtual machine boots with. mkinitrd -k /boot/vmlinux-3.0.13-0.27-pae.gz -i /boot/initrd-3.0.13-0.27-pae[/I] I will let you know how things run after the export… I will do the real migration in two steps, if the client agrees I will first, adjust the kernel with the modules. If that is sufficient the Hyper-V tools are just for interaction from the host to the guest. Grt HB ---

Hi HB, > I’m running the kernel rebuild now… vs. > Re-create the initrd seems I mis-understood you - you’re rebuilding the initial ram disk (which is indeed a required step), not re-compiling the kernel (from source). Sorry for the confusion. Regards, Jens
