Hi, I hope someone can help me out. I'm running into an issue with libvirt 1.2.12 reporting "operation failed: domain is no longer running" for a migration when qemu thinks it was fine. The steps are: 1) create guest with stress test running in it to dirty memory at a high rate (fast enough that it would not normally complete live-migration) 2) trigger live migration with

On libvirt 6.8.0 and qemu 5.1.0, when trying to live migrate "error: internal error: Failed to reserve port" error is received and migration does not succeed: virsh # migrate cartridge qemu+tls://ratchet.lan/system --live --persistent --undefinesource --copy-storage-all --verbose error: internal error: Failed to reserve port 49153 virsh # On target host with debug logs, nothing

Hi, I'm trying to use StatEt IDE for Eclipse as my R editor, but I'm completely lost. I've read all I could find online, made apparently all I had to do (installing rj, configuraing StatEt, etc.) but still cannot make R running. Below is the error log file. Thank you so much for assistance. Matteo !ENTRY de.walware.statet.r.console.ui 1 0 2011-12-05 16:21:51.355 !MESSAGE

I have several hardware and software phones connected to Asterisk 1.2.1 from Debian via SIP or IAX2 and I have defined call transfer codes in features.conf. Everything works with the only exception: When I call a _SIP_ _software_ phone (namely Ekiga or Kphone), I can't transfer the call from the _callee_ via the configured DTMF codes. It seems Asterisk completely ignores the sent DTMF codes

Hi, I posted this message on the StatET-user board last week, but it looks like a ghost-town... I have a bad feeling that there is some code in the plug-in which doesn't work well with my environment, but if I am lucky, maybe other users have worked around this problem somehow - I am hoping that my setup is the issue. Note: very similar StatET setups on 32-bit XP Pro and Vista run

Greetings, I was trying to understand the flow of Migration Code in libvirt and have few doubts: 1) libvirt talks to QEMU/KVM guests via QEMU API. So overall, in order to manage QEMU/KVM guests I can either use libvirt (or tools based on libvirt like virsh) or QEMU monitor. Is it so? 2) Since libvirt is Hypervisor neutral so actual migration algorithm(precopy or postcopy) is present in the

Hi, I would like to clarify how to make snapshots of running VMs with emulated TPM devices. As far as I understand QEMU documentation, it's possible to make snapshots of running VMs with TPM, but it's important to retain the state of swtpm. Does libvirt assist with that in any way or is it completely user's responsibility? libvirt pauses the VM internally when making a snapshot,
