May anybody tell me which is the porpose of virStream functions ? Thanks in advance. Camilo Aguilar -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://listman.redhat.com/archives/libvirt-users/attachments/20100708/ab2a6e86/attachment.htm>

Hello everyone, I am opening a virChannel(unix) to a domain and receiving data with a non-blocking virStream using events, when the connected domain gets stopped(which deletes the channel unix socket) by calling destroy, shutdown, pause or migrate on that domain, with the stream open the read event is triggered repeatedly, and virStreamRecv returns 0 bytes indicating EOF but neither

I tried to dig a bit deeper in this. From my limited understanding, it seems like stream events are implemented as enabled/disabled timers. The issue is that if there's no data from the guest app pending, the timeout in virEventPollRunOnce will be calculated as -1. So then we block on the poll() and only come out once stdin is ready for reading. This means that if data is received from the

I see poll() hanging regardless of guest events. There are indeed two fds in the array (stdin and the other one being the libvirt socket I suppose), but in all cases, I never observed

Doing a few trivial changes to virsh-console does show that it works correctly and pointed out multiple

Hi. I'm try to use virDomainOpenConsole( domainPtr, NULL, stream, VIR_DOMAIN_CONSOLE_SAFE) for control remote terminal, but i don't understand in which text codec the stream returns a data?

That is great, calling Abort also should remove the callbacks.

I just tried removing the callback before calling virStreamFinish and it worked right, I thought by simply finish the stream would stop the events and close it, the example I was based on only calls virStreamFinish on EOF event.

I get just _READABLE events repeatedly, virStreamAbort() doesn't work, it gets out of control after the target domain stops and the unix scocket is deleted. I ended connecting directly to the unix socket. I just wanted to ask if it certainly is a bug or perhaps someone went through this before and have a workaround. Jose V.

the theory , i mean how libvirt get guest's console( or graphic screen), via what kind of channel, then how libvirt show guest's screen. thanks, Eric Blake At 2013-12-28 04:30:30,"Eric Blake" <eblake@redhat.com> wrote: >On 12/26/2013 01:46 AM, yue wrote: >> hi,all >> 1.how to use openConsole and openGraphics? > >See tools/virsh-console.c for an
