Dravigon's questions

So I have a server say server_1 and I have 2 users namely x&y each with their own vms which can't be used by other one since the polkit doesn't allow it to do the polkit rule (in short each vm is named as username*vmname and polkit allows the corresponding user to access it).
Now if multiple servers are used (for vm migration) then i won't be able to interact with that vm in the other machine since my user does not exist in that machine so the polkit won't allow the acess of the vm.

So I thought maybe LDAP can be used But I Think it wont work

So,

1. Is it possible to use LDAP with kvm?
2. If possible How to do it
3. If not any possible solutions

Thank you in advance

I just saw the polkit reference page for libvirt and created the following rule

//content of /etc/polkit-1/rules.d/50-libvirt.rules
polkit.addRule(function(action, subject) {
if (action.id == "org.libvirt.api.domain.getattr" &&
    subject.user == "dravigon") {
      if (action.lookup("connect_driver") == 'QEMU' &&
          action.lookup("domain_name") == 'debian8') {
        return polkit.Result.YES;
      } else {
        return polkit.Result.NO;
      }
}

});

in hopes of limiting the user dravigon only to access the domain debian8 from qemu/kvm driver
but it is not working at all can anyone say where i went wrong

I want to know if it is possible to create a multi user environment using KVM libvirt
that is each user can create there own vm but that must not be accessible by others
saw this Multiuser use of virt-manager
seems like its not working
EDIT1: I want to set owners for each vm
