Hi, for tl;dr people: how we can get uuid or name of a vm within a guest os? description: We are trying to implement a guest-agent for Archipel* to let us run simple commands on guest os**. in archipel each vm has its own jid (jabber id), user will open a chat conversation to vm's jid and send messages like "!exec ls", then we check that user (jid) who sent !exec has permission to run commands on our guest. if he/she had permission we will send a message to jid of guest-agent with message "ls", guest-agent will run command then will send result to vm's jid and we tunnel result to user. now problem is that we don't know (in guest-agent) that what xmpp server we should connect to and what jid is trusted to recieve command from. xmpp server is running on hypervisor and trusted jid is {uuid-of-jvm}@hypervisor.com. right now we've used internal dhcp to set hostname of guest os to something like "uuid-of-jvm.hypervisor.com" using this switch (qemu): -net user,hostname=uuid-of-jvm.hypervisor.com it works but it's not best solution as it only works with qemu and we need a solution that works with other virtualization platforms that libvirt supports. * https://github.com/ArchipelProject/ ** yes, we know about vnc / ssh / ... but by implementing such thing we can add cool stuff in archipel like status of services that are running on guest os. -- regards, behrooz
