Hello,
I do often use the libvirt_lxc containers with userns, and for years
I've used hacky-ish shell scripts to create them, unable to figure out a
sensible way to set them up. Perhaps virt-install is the right tool to
do the job?
Chained up to this message is a patchset that adds the functionality to
virt-install. It is known to have some rough edges (the root password is
unset, does the wrong thing if there are multiple <filesystem>s in the VM,
remote installs are untested), but essentially is able to initialize Debian
and Fedora containers:
virt-install \
--connect lxc:/// \
--name fedora \
--memory 512 \
--idmap
uid_start=0,uid_target=1000000,uid_count=65536,gid_start=0,gid_target=1000000,gid_count=65536
\
--filesystem /var/lib/libvirt/filesystems/fedora,/ \
--location
http://download.fedoraproject.org/pub/fedora/linux/releases/27/Server/x86_64/os
virt-install \
--connect lxc:/// \
--name debian \
--memory 512 \
--idmap
uid_start=0,uid_target=1000000,uid_count=65536,gid_start=0,gid_target=1000000,gid_count=65536
\
--filesystem /var/lib/libvirt/filesystems/debian,/ \
--location http://ftp.us.debian.org/debian/dists/testing/
Does this approach look sensible? Does it make sense to address the
known issues in this and merge the functionality to virt-manager or
should this perhaps belong to a separate tool?
The diffstat looks optimistic.
