similar to: Unable to connect to vmchannel on host when the VM is started via libvirt

This set of 10 patches removes the need for any vmchannel implementation, although we can still choose to use vmchannel if we want. In this so-called "null vmchannel" configuration, the appliance connects directly to a port on the library. The exact method is described in patch 9/10. This method still requires SLIRP (user mode networking) so it is not a panacea, because recent

The change to "null vmchannel" didn't get reflected in the configure script which still checks for vmchannel in qemu. This patch tidies up this part of the configure script so we don't fail, provided we have support for user mode networking (which is required for null vmchannel). This patch didn't make it into 1.0.71. Rich. -- Richard Jones, Emerging Technologies, Red

Hi all. Having trouble figuring out the magic to set up VMChannel comms between EL6.x host/guests. My end goal is to enable fence_virt in the guest to talk to fence_virtd on the host via VMChannel. I'd prefer to use that instead of multicast because it is supposed to work even if networking in the guest is down/borked. My analysis is that there is a mismatch between what libvirt is feeding

Hi, I am trying to set up vmchannel between the host and guest os. However, "sudo virsh start vm1" always gave me this error: ************************************************************* error: Failed to start domain vm1 error: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 bind(unix:/tmp/foo): Permission denied chardev:

Hi All, I?m trying to do ?things? after my Dial application terminates (e.g. play IVR to called party, calling party, etc.). I?m trying to use the local channel for this purpose but so far with no success. I?m using 1.6.1.18 and this is my extensions.conf: [Internal] exten => _22,1,Dial(Local/${EXTEN}@CW/n) ; 22 is test number exten => _22,2,Noop(After Hangup) [CW] exten =>

This patch is for discussion only. The multiport virtio-console is not accepted upstream, and in any case is currently being rewritten for the nth time. Getting a test environment to test this out is also non-trivial. It look me about a day. You need to compile the alternate qemu (see URL in the patch + attached qemu patch on top of this). You also need to compile the alternate kernel - NOTE:

And with that, guestfish works on Mac OS X. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler.

Notes: (1) Tis doesn't completely remove legacy serial ports yet. I couldn't work out how to make the Linux kernel see the virtconsole, so that is still using a serial port. (2) The guest network is completely unavailable if you apply this patch. We will need to add this back, possibly as an optional feature. Rich. -- Richard Jones, Virtualization Group, Red Hat

Our setup: Windows AD realm with ~115K users (and numerous groups etc) FreeBSD servers with Samba 4.7.6 and Samba 4.9.3 (both show the same growth) We just noticed that one of the ‘winbindd’ daemons on the servers seems to be growing and growing forever. A bit of detective work pointed us at the “wbinfo -u” command being that culprit. As part of a systems monitoring script we ran that once a

There is a need for communication channel between host and various agents that are running inside a VM guest. The channel will be used for statistic gathering, logging, cut & paste, host screen resolution changes notifications, guest configuration etc. It is undesirable to use TCP/IP for this purpose since network connectivity may not exist between host and guest and if it exists the traffic

This patch is in preparation for allowing libguestfs to use alternate "vmchannel" implementations. Although it's not a functional change, I think it is worthwhile on its own because use of the term "vmchannel" in the names of constants is inappropriate since (a) the "-net channel" option is now properly known upstream as "guestfwd", and (b) no one can

This also changes the name of the "vmchannel" buffer to just "buf", reflecting the fact that it's just used as a temporary buffer, and that the word vmchannel is overloaded.

I think performance is not just about your xml, the host system will have a bigger impact.

There's a new syntax check rule from gnulib. It requires that you write e.g., exit (EXIT_SUCCESS), not exit (0). And the same for 1/EXIT_FAILURE and any other constants. There were a lot of violations, including a few false positives, so I started with the exemptions (see the .x-sc file below). Then I converted the vast majority automatically, with this: maint: use EXIT_SUCCESS and

List, I have a number of Windows 2016 servers I am deploying, but I’m having some I/O performance issues. I have done all of the obvious things like virtio drivers, but am finding there is more performance to be found with hyper-v extensions, how we virtualize the hardware clock, and iothreads. I’m using ZVOLs to back the VM, and I’m using 4k block sizes, which seems to offer the best 4k random
