How to check which hypervisor is used from my VM?

Question

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, Sep 10 '20 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 Feb 18 '19 at 05:07

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 Sep 18 '13 at 12:44
Simple and concise, this is the best answer for me. – Luis Vazquez Sep 10 '20 at 21:44
