KvmOnGentoo

Requirement

• a Gentoo install on a vt (Intel) or svm (AMD) machine
• kernel compiled with at least, either y or m

     CONFIG_HAVE_KVM=y
     CONFIG_HAVE_KVM_IRQCHIP=y
     CONFIG_HAVE_KVM_EVENTFD=y
     CONFIG_KVM=y

     and CONFIG_KVM_INTEL=y or CONFIG_KVM_AMD=y depending if you are using Intel or AMD CPU
     
     optionally (if you want to use vhost)
     CONFIG_VHOST_NET=y

Installing

• printf '%s\n' 'QEMU_SOFTMMU_TARGETS="i386 x86_64"' 'QEMU_USER_TARGETS="i386 x86_64"' >> /etc/protage/make.conf

(If you haven't migrated /etc/make.conf to /etc/protage/make.conf yet, use /etc/portage instead or migrate it to /etc/protage/make.conf)

• emerge app-emulation/qemu-kvm

Network setup

Bridged

• edit /etc/conf.d/net

     config_eth0="null" # any any other interfaces you want to bridge
     bridge_brkvm="eth0"
     config_brkvm="192.168.254.254/24"  # the ip of the original eth0, or dhcp
     brctl_brkvm="setfd 0
        sethello 30
        stp off"

• cd /etc/init.d
• ln -s net.lo net.brkvm
• rc-update add net.brkvm default
• rc-update del net.eth0 default

VM start/stop

• there are no standard Gentoo way to do this, you will need 3rd party scripts/front-ends.
