libvirt users - Apr 2020 - Re: [Query] Facing issue in build libvirt6.0 on ubuntu 1804

Hi all,

I am trying to build libvirt 6.0 on ubuntu OS 18.04.
Facing one issue libvirt source compilation.

===========================================<stdin>:215: (ERROR/3) Error in
"code-block" directive:
1 argument(s) required, 0 supplied.

.. code-block::

   help [command-or-group]


<stdin>:229: (ERROR/3) Error in "code-block" directive:
1 argument(s) required, 0 supplied.

.. code-block::
==========================================
*Source:* https://libvirt.org/sources/libvirt-6.0.0.tar.xz

*Build Command*:
$ mkdir build && cd build
$ ../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install

Need help in solving the build error.
is it possible to install libvirt package without build
if yes please share the command/procedure/link.

Thanks,
Ramesh

More context would be helpful, but this looks like rst2man or rst2html 
failed. Again, context would be helpful to know which one and whether 
it's caused by a problem in our released code or rst2*.

Last time someone reported this problem it was due to an outdated
local / pip install of the python3-docutils package

Our CI passes on Ubuntu 18.04, so we know it works with the official
distro provided python3-docutils Deb package.

Daniel

Ah, so you wanted to use 'virsh qemu-attach' to attach libvirt to a 
running qemu. Yeah, it needs a monitor. However, the functionality was 
not maintained and probably not functional anyway so we've removed in 
the 5.5.0 release.

But what's interesting is that you are unable to build. Which package is 
providing the rst2* binaries? Are their up to date?

Michal

Hi Michal,

Please find the details below,
rst2html5 1.10.6 (Docutils 0.16 [release], Python 3.6.9, on linux)


is there any other way to access/control the guest os running on top QEMU ?

Thanks,
Ramesh

Hi Daniel,

Thanks for command.
Can I install specific version of prebuilt libvirt ?

Eg: version 6.0
