#KVM QEMU DRIVER#
The video driver needed for Xorg inside QEMU is xf86-video-modesetting. If on your host you now add a MASQUERADE rule for tap0 to your host's default nic, and you turn on ip_forward on your host, you can now do svn updates, surf, run tranmission, etc right from your qemu guest. This option also takes other CPU-related parameters, such as number of sockets, number of cores per socket, or number of threads per core.
#KVM QEMU PC#
In your alpinebox, create an interfaces file like this: QEMU supports up to 255 CPUs on the PC platform (up to 64 with KVM acceleration used). The qemu-ifup script is what does that for the host. So you need to assign ip addresses to BOTH sides of the tunnel. What's actually happening is you are effectively creating a point-to-point tunnel, with the phys tap0 device being one endpoint, and the virtual box's eth0 being on the other point of the tunnel. Now your alpine guest will have 3 NICs, mapped to tap0, tap1, and tap2 respectively. net tap,vlan=0,ifname=tap2,script=./qemu-ifup -net nic,vlan0 \ net tap,vlan=0,ifname=tap1,script=./qemu-ifup -net nic,vlan0 \ To create a qemu guest with more than one nic, just repeat the -net commands Qemu -net tap,vlan=0,ifname=tap0,script=./qemu-ifup -net nic,vlan0 \ So to have a single NIC on the qemu virtual system that is connected to tap0 on the physical host: You need 2 net commands on the command line interface, one for the host: The key is to define the virtual network interface on the correct virtual vlan, and the correct ifup script. To get networking running correctly, you can use the tun/tap interface, which then becomes a real interface. The next reboot then loads the generated apkovl and apkcache found on /dev/vda1 - completely running-from-ram based on the latest official ISO.
#KVM QEMU INSTALL#
QEMU can be installed from Homebrew: brew install qemu. Setup-alpine # (select vda1 for saving configs) QEMU is packaged by most Linux distributions: Arch: pacman -S qemu. drive file=/media/usb/images/nfig,if=virtio \Īnd inside the KVM (running Alpine Linux):Įcho "/dev/vda1 /media/vda1 vfat rw 0 0" > /etc/fstab It's fast) If you are not ready to build Linux kernel modules but want to get started, check out my guide on running Windows 2000 with QEMU on WSL.

Qemu-img create -f raw /media/usb/images/nfig 32M They have said Linux KVM guest support is coming. This works by mounting a persistent filesystem under /media and selecting it to store the apkovl and the apkcache.
