Why does the Hyper-V host not recognize LIS on the CentOS 7 machine?
Hyper-V Manager Version 6.3.9600.16384
uname -r shows 3.10.0-123.el7.x86_64
lsmod shows hv_storvsc, hv_netvsc, hv_utils and hv_vmbus loaded.
modinfo hv_utils shows version 4.0.7
dmesg shows the host recognized: Hyper-V Host Build:9600-6.3-17-0.17039; Vmbus version 3.0 and other messages that seem to indicate data is received from the host, such as hyperv_fb: Screen resolution: 1152x864, Color depth: 32
However, Get-VM | ft Name, IntegrationServicesVersion shows a blank field while other VMs show a version. The Hyper-V Manager "Integration Services:" field is likewise blank, and the SCVMM "VM Additions" column for the VM shows "0.0".
Best Answer
You only have the parts of Hyper-V support which are included with the Linux kernel. You don't have the daemons installed which talk to Hyper-V to report guest-side status and such.
Here's a link which discusses installing these.
