Get help with HNS VM installation error

[gdr...@gmail.com]

Hi,

I'm trying to install a VM in HVM mode called HNS (hybrid network simulation).

Based on Debian, HNS seems to run on KVM/QEMU.

I followed the step-by-step installation instructions : https://www.hynesim.org/installation-pas-a-pas/

Edit /etc/hynesim/hynesim-node.ini

Add support for KVM/QEMU :

KvmQemu/dummy = 1

I am having an issue relating to kvm_intel module into the Qubes OS 4.0 environment.

Cleanup prior to restarting the hynesim-node service :

$ /etc/init.d/hynesim-node cleanup
[...]
Failed to stop vboxdrv.service: Unit vboxdrv.service not loaded.
modprobe: ERROR: could not insert 'kvm_intel': Operation not supported
Module unloading failed: kvm_intel
[...]

How can I fix it ?

Any help and advice would be greatly appreciated.

Best regards.

Running a hypervisor like KVM inside another hypervisor like Xen is
known as "nested virtualization". This is disabled and not supported in
Qubes.

I think that gdrub51 is saying that HNS runs under KVM, and they want to
run it under Qubes, *not* that they are trying to run KVM within Qubes.

In any case, I dont believe that nested virtualization is "disabled"
under Qubes. Not suppported certainly, but that's different.

OK.

Don't believe nestedhvm=1 out of the box. Ergo, it's disabled (at least
for type 1 hypervisors). :)

Hi,

8.1.4   Importing virtual machines (p40) : https://brage.bibsys.no/xmlui/bitstream/handle/11250/216822/ADalmo_MGKnudsen_JLovbraten.pdf

"Hynesim is not a hypervisor in itself, and therefore relies on other software to do the creation and running of the virtual machines."

Those discussions are pretty old, and no longer apply to the current
situation.

nestedhvm=1 is a parameter set at the VM level. It need not be set to
get nested virtualization in Qubes4.0

I regularly run Qubes nested, both Live images and installed HVMs, and
it requires no special parameter setting. Both Live and installed work
out of the box - there's certainly nothing disabled.

Interesting, thanks. Hadn't seen anywhere the situation had changed!
