[meta-virtualization] [PATCH 0/4] xen 4.3.0 recipe and updated xen-image-minimal

[Chris Patterson]

This set of patches should provide a user with the ability to generate a xen 4.3.0 based dom0 image.

[NOTES]

With these patches, xen-image-minimal requires "xen" and "aufs" to be present in DISTRO_FEATURES to function correctly.  

[DISTRO TESTING]

This image has been tested using:

machine=sugarbay
DISTRO_FEATURES += " aufs xen"

[BUILDING IMAGE]

bitbake xen-image-minimal

[QEMU BUILD TESTING]

To start up and test core-image-xen using kvm on hardware supporting nested virtualization:

kvm -hda deploy/images/xen-image-minimal-sugarbay.hddimg -cpu host -no-kvm-irqchip -m 4096 -net nic,model=e1000 -net user -serial stdio

..or..

kvm -hdc deploy/images/xen-image-minimal-sugarbay.iso -cpu host -no-kvm-irqchip -m 4096 -net nic,model=e1000 -net user -serial stdio

[XEN TESTING]

To test the runtime core-image-xen and boot a debian PV virtual machine:

# bring up networking
ifconfig eth0 up
brctl addbr br0
brctl addif br0 eth0
udhcpc -i br0

# place test debian vm in /test/debian
mkdir -p /test/debian
cd /test/debian

# pull example kernel, initrd
wget http://ftp.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/xen/initrd.gz
wget http://ftp.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/xen/vmlinuz

# create 4G disk
truncate -s 4096M disk.img

cat > debian.cfg << EOF
kernel = "/test/debian/vmlinuz"
ramdisk = "/test/debian/initrd.gz"
extra = "debian-installer/exit/always_halt=true -- console=hvc0"
vif = ['bridge=br0']
memory = "256"
name = "debian"
disk = ['file:/test/debian/disk.img,xvda,w']
EOF

xl -v create -d debian.cfg

xl console debian

Chris Patterson (4):
  linux-yocto: add kernel fragment and scc for xen dom0 kernel support.
  linux-yocto: add optional support for aufs and xen using
    DISTRO_FEATURES.
  xen: add 4.3.0 recipe.
  xen-image-minimal: update image to support xen 4.3.0 base with xl
    toolstack.
