[libvirt] [PATCH LIBVIRT] libxl: Recognise ARM architectures
Only tested on v7 but the v8 equivalent seems pretty obvious.
XEN_CAP_REGEX already accepts more than it should (e.g. x86_64p or x86_32be)
but I have stuck with the existing pattern.
With this I can create a guest from:
<domain type='xen'>
<name>libvirt-test</name>
<uuid>6343998e-9eda-11e3-98f6-77252a7d02f3</uuid>
<memory>393216</memory>
<currentMemory>393216</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='armv7l' machine='xenpv'>linux</type>
<kernel>/boot/vmlinuz-arm-native</kernel>
<cmdline>console=hvc0 earlyprintk debug root=/dev/xvda1</cmdline>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<disk type='block' device='disk'>
<source dev='/dev/marilith-n0/debian-disk'/>
<target dev='xvda1'/>
</disk>
<interface type='bridge'>
<mac address='8e:a7:8e:3c:f4:f6'/>
<source bridge='xenbr0'/>
</interface>
</devices>
</domain>
Using virsh create and I can destroy it too.
Currently virsh console fails with:
Connected to domain libvirt-test
Escape character is ^]
error: internal error: cannot find character device <null>
I haven't investigated yet.
