So I'm running a VM somewhere and want to know what hypervisor the host is running. Any way to check whether it's running KVM or in a container?
The vm is running Ubuntu

This question should be removed because is a duplicate of the one above, which is more precise and with far more detailed responses.Luis Vazquez– Luis Vazquez2020-09-10 21:47:17 +00:00Commented Sep 10, 2020 at 21:47

Without external tools:
sudo dmidecode | grep -i -e manufacturer -e product -e vendor
or
sudo grep -i -e virtual -e vbox -e xen /var/log/dmesg # or /var/log/kern.log
should give you enough to go on.
You can see checks for specific platforms in the ImVirt module.

This doesn't work, at least for xen. It shows the platform's specifications even in a vm.Fake Name– Fake Name2019-02-18 05:07:04 +00:00Commented Feb 18, 2019 at 5:07
Look at virt-what
stephenm@pc:~$ apt-cache search virt-what
virt-what - detect if we are running in a virtual machine
sudo apt-get install virt-what
sudo virt-what

This is how
facter(puppet) determines the VM type.jordanm– jordanm2013-09-18 12:44:57 +00:00Commented Sep 18, 2013 at 12:44 -
