This chapter contains various notes on configuration and setup of the host system (Linux), and the hypervisor (QEMU) to use either pass-through or emulate various technologies for the nrkernel and develop for it.
Make sure the QEMU version for the account is is >= 6 . The following steps can be used to build it from scratch, if it the Ubuntu release has a lesser version in the package repository.
First, make sure to uncomment all #deb-src lines in /etc/apt/sources.list if not already uncommented. Then, run the following commands:
sudo apt update sudo apt install build-essential libpmem-dev libdaxctl-dev ninja-build apt source qemu sudo apt build-dep qemu wget https://download.qemu.org/qemu-6.0.0.tar.xz tar xvJf qemu-6.0.0.tar.xz cd qemu-6.0.0 ./configure --enable-rdma --enable-libpmem make -j 28 sudo make -j28 install sudo make rdmacm-mux # Check version (should be >=6.0.0) qemu-system-x86_64 --version
You can also add
--enable-debug to the configure script which will add debug
information (useful for source information when stepping through qemu code in
