as well, but seems like if I follow the default configuration example, I
get this:
virsh # create /etc/libvirt/lxc/axant.xml
errore: Impossibile creare il dominio da /etc/libvirt/lxc/axant.xml
errore: unknown OS type exe
[sorry for the Italian message, but it doesn't really matter]
The configuration is this:
<domain type='lxc'>
<name>axant</name>
<memory>14680064</memory>
<os>
<type>exe</type>
<init>/init</init>
</os>
<vcpu>8</vcpu>
<clock offset="utc" />
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<filesystem type='mount'>
<source dir='/media/chroots/axant'/>
<target dir='/'/>
</filesystem>
<interface type='bridge'>
<mac address="8e:8b:e5:aa:28:b6" />
<source bridge="br0" />
</interface>
<console type='pty' />
</devices>
</domain>
am I doing something wrong or the doc at [1] is outdated somehow?
[1] http://libvirt.org/drvlxc.html
What is the output of 'virsh --connect lxc:/// capabilities'? Mine looks like:
<capabilities>
<host>
<cpu>
<arch>x86_64</arch>
</cpu>
<topology>
<cells num='1'>
<cell id='0'>
<cpus num='2'>
<cpu id='0'/>
<cpu id='1'/>
</cpus>
</cell>
</cells>
</topology>
</host>
<guest>
<os_type>exe</os_type>
<arch name='x86_64'>
<wordsize>32</wordsize>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<domain type='lxc'>
</domain>
</arch>
</guest>
</capabilities>
And I can define your posted config without error. If you don't have a guest
block, defining any guest will fail, so the lxc capability detection probably
needs to be taught how to work with your system. You can checkout out
src/lxc/lxc_conf.c:lxcCapsInit
