Re: [vdsm] new API verb: getVersionInfo()

If we want to support migration, I think we should implement console server out of vdsm. Actually, It will work like proxy. So we call it as consoleProxy now. That consoleProxy can deploy on same machine with engine, or standalone, or virtual machine. I think its' working flow as below: 1. user request open console to engine. 2. engine setTicket(uuid, ticket, hostofvm) to consoleProxy. consoleProxy need provide api to engine. 3. engine return ticket to user. 4. user 'ssh UUID@consoleProxy' with ticket. 5. consoleProxy connect 'virsh -c qemu+tls://hostofvm/system console'. the host of running consoleProxy should have certificates of all vdsm host. 6. consoleProxy redirect output of 'virsh -c qemu+tls://hostofvm/system console' with ssh protocol. Same with currently implement. we can use system sshd or paramiko. If we use paramiko, it almost reuse the code of consoleServer that I have already writen. After vm migrated: 1. engine tell consoleProxy that vm was migrated. I guess engine can know vm finished migration? And engine how to push the event of vm finished migration to consoleProxy? Engine only have rest api didn't support event push? Is streaming api can resolve this problem? 2. consoleProxy kill 'virsh console'. 3. reconnect to new host of vm with 'virsh console' again. There will missing some character if the reconnection isn't enough fast. This is hardly to resolve except implement ssh in qemu. I guess streaming api have some problem too. 4. continue redirect 'virsh console'. Actually if we implement consoleProxy out of vdsm, we don't need decide it will run on physical machine or virtual machine now. A lot detail need to think. I'm not cover all problem. And I haven't code to prove that work now. Just depend on thinking. Is this make sense? How is this handled with current displays like VNC and Spice? Extending spice to provide just serial console remoting actually seems the easiest way to provide remote text-only console because most of the code path is already mature (used for client to guest agent communication) and e.g. spicy to just provide a device where e.g. screen could connect or just provide the console itself. CCing spice-devel would it allow users to script with/over it like they can with ssh? If I understand correctly the idea is to add another channel for spice that would connect to a char device in qemu that in turn connects to a serial port. The result is a spice client that can display and interact, but not a scripting extension. We could also create a unix domain socket to expose this connection on the client, and the client could then use that for scripting (but this will be instead of displaying, since you can't multiplex the console in a meaningful way - unless you run screen/tmux over it maybe): remote-viewer --spice-console-unix-domain-socket /tmp/spice.uds (This option assumes we want a single console channel - if we have multiple we will need to name them too) Anyone will be able to script it using for instance: socat UNIX-CONNECT:/tmp/spice.uds SYSTEM:echo hello world We could also turn it into a pty (socat can do that). i think using spice this way may be a very good solution, to proxy a serial console. only caveat is it requires client to install spice, vs. just using ssh. ___ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel

Distinguishing VM by vmUUID. The current implement was vdsm will allocated port for console dynamically and spawn sub-process when VM creating. In sub-process the main thread responsible for accept new connection and dispatch output of console to each connection. When new connection is coming, main processing create new thread for each new connection. Dynamic port will allocated port for each VM and use range port. It isn't good for firewall rules. so I got a suggestion that use fix port. and connect console with 'ssh vmuuid@hostip -p fixport'. this is simple for user. We need one process for accept new connection from fix port and when new connection is coming, spawn sub-process for each vm. But because the console only can open by one process, main process need responsible for dispatching console's output of all vms and all connection. So the code will be a little complex then dynamic port. So this is dynamic port VS fix port and simple code VS complex code. From a usability point of view, I think the fixed port suggestion is nicer. This means that a system administrator needs only to open one port to enable remote console access. If your initial implementation limits console access to one connection per VM would that simplify the code? Yes, using a fixed port for all consoles of all VMs seems like a cooler idea. Besides the firewall issue, there's user experience: instead of calling getVmStats to tell the vm port, and then use ssh, only one ssh call is needed. (Taking this one step further - it would make sense to add another layer on top, directing console clients to the specific host currently running the Vm.) I did not take a close look at your implementation, and did not research this myself, but have you considered using sshd for this? I suppose you can configure sshd to collect the list of known users from `getAllVmStats`, and force it to run a command that redirects VM's console to the ssh client. It has a potential of being a more robust implementation. I have considered using sshd and ssh tunnel. They can't implement fixed port and share console. Would you elaborate on that? Usually sshd listens to a fixed port 22, and allows multiple users to have independet shells. What do you mean by share console? Current implement we can do anything that what we want. Yes, it is completely under our control, but there are down sides, too: we have to maintain another process, and another entry point, instead of configuring a universally-used, well maintained and debugged application. Think of the security implications of having another remote shell access point to a host. I'd much rather trust sshd if we can make it work. Dan. At first glance, the standard sshd on the host is stronger and more robust than a custom ssh server, but the risk using the host sshd is high. If we implement this feature via host ssd, when a hacker attacks the sshd successfully, he will get access to the host shell. After all, the custom ssh server is not for accessing host shell, but just for forwarding the data from the guest console (a host /dev/pts/X device). If we just use a custom ssh server, the code in this server only does 1. auth, 2. data forwarding, when the hacker attacks, he just gets access to that virtual machine. Notice that there is no code written about login to the host in the custom ssh server, and the custom ssh server can be protected under selinux, only allowing it to access /dev/pts/X. In fact using a custom VNC server in qemu is as risky as a custom ssh server in vdsm. If we accepts the former one, then I can accepts the latter one. The consideration is how robust of the custom ssh server, and the difficulty to maintain it. In He Jie's current patch, the ssh auth and transport library is an open-source third-party project, unless the project is well maintained and well proven, using it can be risky. So my opinion is using neither the host sshd, nor a custom ssh server. Maybe we can apply the suggestion from Dan Yasny, running a standard sshd in a very small VM in every host, and forward data from this
Re: [vdsm] new API verb: getVersionInfo()
I don't see how pyinotify is even related to storage stats. It doesn't work with NFS and is a bit flaky when it comes to VFSs like proc or dev. Also it doesn't check liveness or latency so the events don't really give us anything useful. The data is being taken from cache. I assume there is a prepare call there that makes everything slower.

Instead of calling multiple commands we will call one that does everything. skip / Can I please make a small note, before we went too deeply into getVdsCapabilities() discussion. What the getVdsCapabilities returns now, it is, literally speaking, *host*info*. That means some reasonable description of the host — installed packages, cpu topology, so on, so forth. … What I propose, is just a dedicated call, that will not carry «all-in-one» info, but only the *version* information. By historical reason there are several meanings of the «version» term in the context of the VDSM — that is VDSM version, RHEV version, cluster versions… But nevertheless. I would stress again: * *not* the host info * *not* the installed packages list * *not* the installed hardware specifications Maybe even not the current weather conditions outside of the datacenter. But only supported *versions* of VDSM *protocols* (API versions). … Returning the version can be done in a fast, reliable manner — yes, I know that one can implement fast cache for rpm queries and so on, but please think: can *any* caching be more reliable and more fast than returning several constant literals? The version information is the basic and vital info in the mixed environment with several versions of the same software. It can be queried often, it must be as simple as it can be at all. That's why I proposed a dedicated API call, that does nothing but returns the version. ___ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel

… Just to be clear: yes, I think, that getVdsCapabilities() can and should be optimized, but as well it has quite different meaning for different purposes. And what about capabilities «bag» — its format also can be a subject of a change (e.g. long int bitmask ⇒ list of literals), but the version can always remain the version. ___ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel
