Adventures in Installing Linux Integrations Service 4.1 for Hyper-V

JaredBusch

So after testing out the Snipe setup last night I decided to try and up date the Linux Integration Services (LIS) on my test box.

Like many things on CentOS/RHEL the LIS version is quite old and I have been having a problem that I cannot snapshot a running VM. I am assuming because of the LIS not working right.

After poking around enough, I finally got the right download link from MS and made use of the firefox feature to right click on a download and get the download URL.

I then used wget to download it to the server directly, extracted, and installed.

After the reboot, the system never came online.

All I could see in the Hyper-V manager windows was the progress bar on the bottom of the screen.

So I blew it up and just started a new CentOS7 VM.

So a new, clean server, not even a yum update yet.

yum -y install wget
wget https://download.microsoft.com/download/7/6/B/76BE7A6E-E39F-436C-9353-F4B44EF966E9/lis-rpms-4.1.3-2.tar.gz
tar xvzf lis-rpms-4.1.3-2.tar.gz
cd LISISO
./install.sh

[root@snipeit LISISO]# ./install.sh

Well, that went better.

But Hyper-V Manager still says an update required....

Similar to what I see in Fedora 25, I now do see IP info though.

Initial yum update now done and that included a kernel update.
0_1494349269152_upload-76a25147-8b11-48b1-a6d4-6415f81663a8

The MS document talks a bit about the running kernel version and cleaning up older ones. Possibly this broke my prior test.

Time to reboot and find out.

All good.

No idea WTF happened last night. Well other than it being 1am

dbeato

@JaredBusch So after the update did it show as updated? Usually I need to do that from time to time with Hyperv or Xenserver.

Hyper-V still shows it as above. Update required and Degraded. BUt it is in and running current.

@JaredBusch dumb question: did you check all services are up and running?

systemctl status | grep hv
       │   │ └─10000 grep --color=auto hv
         ├─hv-kvp-daemon.service
         │ └─563 /usr/lib/linux-tools/4.8.0-49-generic/hv_kvp_daemon -n
         ├─hv-vss-daemon.service
         │ └─577 /usr/lib/linux-tools/4.8.0-49-generic/hv_vss_daemon -n

on my ubuntu machines the fcopy is always down. don't know why... but I do not need it.
May be somthing is not running and hyperv badly detects the event
