similar to: Bug? virGetLastError() returns NULL after virDomainCreate() if Domain running already

Hi, Sometimes when stopping a virtual domain using virDomainDestroy(), I come across a domain that is already stopped. (For example when someone already stopped the domain manually using virsh or because the guest OS issued a shutdown.) This is a special case that I absolutely need to catch and handle. Unfortunately, when this happens, and I call virGetLastError() afterwards, I always just

libvirt version: 3.4.0 architecture: x86_64 ubuntu16.04-server hypervisor: kvm,qemu I call virDomainCreate create a transient vm, After a period of time ,I call virDomainDestroy, the vm configure is stil exist， the vm turn to persistent, I don't known the reason. Thanks

Hi, I'm experiencing weird things with the vbox driver when using multiple threads. Following is the snippet of code I experience problems with /*****************************************************/ #include <stdlib.h> #include <stdio.h> #include <pthread.h> #include <libvirt/libvirt.h> void *create_and_destroy(void *arg) { virDomainPtr dom = (virDomainPtr)arg;

Libvirt has a fixed 15 second timeout for qemu to exit. If qemu is writing to a slow USB key, it can hang (in D state) for much longer than this - many minutes usually. The solution is to check specifically for the libvirt EBUSY error when this happens, and retry the virDomainDestroyFlags operation (indefinitely). See also the description here:

Hi, we experienced a strange, non-reproducible error after a successful migration to another host. When we called virDomainDestroyFlags with VIR_DOMAIN_DESTROY_GRACEFUL flag after the migration on the source host, we got VIR_ERR_OPERATION_INVALID (code 55) error. The same with repeated virDomainDestroyFlags calls. Normally, we would expect either success or VIR_ERR_NO_DOMAIN error. `virsh

I rebooted my machine and now when trying to run a "vm ... virsh create /etc/xen/vm1.xml" I am getting the following error: libvirtError: virDomainCreate() failed POST operation failed: (xend.err ''Device 0 (vkbd) could not be connected. Hotplug scripts not working.'') I tried restaring xend and even mounting and unmounting the partition that holds the vm and still no

Hi, all. I want to know when I press run button. start a domain. What is the procedure of libvirt internal. I know it will call virDomainCreate(),then qemuDomainStart() -> qemuDomainStartWithFlags(). what is the next? xuanmao_001 -------------- next part -------------- An HTML attachment was scrubbed...

Hey there, im using libvirt since 2 weeks now and there are still some issues im confronted with. I use libvirt in C# and I'm running a 32-bit machine on Windows 7. Actually my worst problem is, is that I'm not able to Shutdown on machine no matter which command I'm using. virDomainShutdown isn't working nor virDomainDestroy. Basically I use the virConnectOpenAuth example to make a

Hi, I have noticed that virt-manager has the ability to show me the current cpu- and memory-usage of both the host and running guest machines. How does it do that? I could make good use of that information myself in the client applications I'm writing, however, from what I can see on http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about getting it from libvirt. In

Hi All, I am new using libvirt. I kept on getting the following error when I try to start my VM. Can anyone give me any suggestion on what could went wrong?

Hi, I have a Centos 5 box with dom0 and several domUs and one of them is not runnable. I ran updates several days ago and the update included a kernel update so I used virt-manager to reboot. But it won't book. It shows as not running and when I try to run it I get a dialog box with this: Traceback (most recent call last): File
