One thing at a time, though. First, how do we get the vstorage commands included in the CentOS 7 container? What packages need to be installed, and from what repository?
The repo is http://repo.virtuozzo.com/vz/releases/7.0/x86_64/os
vstorage binary is in vstorage-ctl package and vstorage-mount binary is in vstorage-client package.
However vstorage binary is not used at all the driver. Also the openvz driver for example does not check for its binaries. Probably vstorage driver should be changed accordingly as binaries are not build requisites.
I'm not sure how the best way to handle the situation is. You should look at what we do with qemu-img for inspiration.
As an aside, I'm still very confused by the vz/openvz dichotomy. AFAICT, the latter can be (and in fact is) built unconditionally, but the former requires the "Parallels SDK" packages to be installed: baffingly enough, said SDK is obtained from the repository mentioned above, which just so happens to include the string "openvz" twice in its URL...
Yeah, naming is confusing. Basically openvz manages system containers thru vzctl binary. Vz driver manages both VMs/containers thru single connection using prlsdk. And originally vz driver was called parallels driver but after company split we have to change the name. Also in the past prlsdk was only commercially available and now times changes and both vzctl and prlsdk are available under openvz name which is an umbrella for uncommercial projects.
Thanks for the explanation, but I'm afraid that even with it the relationship between the various projects and products is only marginally clearer to me O:-)
Anyway.
Starting from our existing CentOS 7 build environment, I've added
[vz] baseurl=http://repo.virtuozzo.com/vz/releases/7.0/x86_64/os/ enabled=1 gpgcheck=1 priority=90 includepkgs=vstorage*,libvz*
to /etc/yum.repos.d/vz.repo and tried to install vstorage-client. That failed with
Error: Package: vstorage-libs-shared-7.10.1.5-1.vz7.x86_64 (vz) Requires: libjson-c.so.2(libjson-c.so.2)(64bit)
which is surprising because I have the json-c package installed. I think that's caused by a bug in your spec file - the name of the library should not appear in parentheses - but I can't seem to find the source package for vstorage-client under
Yes, this dependancy is clearly broken, whcih is the reason why we're not using the URL you show above, and instead using the older release at: https://download.openvz.org/virtuozzo/releases/openvz-7.0.11-235/x86_64/os/ this URL is the last one that doesn't have the broken dependancies. I asked about this at the time but didn't get any response, so I guess it was buried in the email torrent and then i forgot to ping about it. https://www.redhat.com/archives/libvir-list/2019-December/msg00437.html Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
