Hi , maybe someone can help with the following topic.
On x86_64 there is for quite some time coding in the JVM to detect the virtualization (e.g. VMWare, KVM, Xen …) .
The info is later used in hs_err file output / jfr etc .
See
https://github.com/openjdk/jdk/blob/34cdda5b8359cce33c2d4f92a41a620aea4f96e…https://github.com/openjdk/jdk/blob/34cdda5b8359cce33c2d4f92a41a620aea4f96e…
(x86_64 uses the cpuid call)
On Linux ppc64(le) we have something similar (but this parses some /proc file system location ).
I think it would be nice to have the Virtualization detection on Linux aarch64 too .
Is someone aware of some good ways to get the info on aarch64 ?
On OS level , we can for example call this to get the info :
sudo dmidecode -s system-product-name
KVM Virtual Machine
(but calling stuff like dmidecode from the JVM is not really an option , and it also needs privileges [sudo] ) .
For the JVM we need something more lightweight (like cpuid call on x86_64 , or parsing a file on ppc64(le) ) .
