I am trying to write a simple app which connects a channel obtained from virDomainOpenChannel() to stdin/stdout (based in part on the snippet at [1]). However, it seems like the data received back from the stream is delayed by one iteration. It would be hard to explain this by simply showing the output, so here's a timeline instead: 1. start the program on the host 2. write "msg from

Hello, I am searching for the libvirt operations for relocating LXC (system or application) containers. LXC relocation mechanism is done by checkpoint / restart. I went over libvirt API documentation and found the following methods: virDomainSave that receives a domain and path to state file. The method saves domain's memory contents into a disk file. virDomainRestore that receives a domain

Hi, I have a question about file permissions and how they are affected by a client's umask. To illustrate my question, I issued the following commands first on a local ext3 file system and then on a cifs file system: $ umask 0002 $ touch f1 $ echo xx > f2 $ umask 0022 $ touch f3 $ echo xx > f4 $ ls -l On Ext3, the output is: -rw-rw-r-- 1 abdv29 users 0 Oct 9 00:31 f1 -rw-rw-r-- 1

Hi buddy, I wanna to monitor a domain's life cycle event, so i register a event an a virConnectDomainEventCallback, the code segment is as below: ------------------------ int DomainEventCallback(virConnectPtr conn, virDomainPtr dom, int event, int detail, void * opaque){ /*My code */ ....... } int main(){ /* .....*/ virDomainPtr dom =

Hi, everyone I'm writing application using libvirt and I need call virDomainGetCPUStats to get domain cpu stats . I learn from API reference that this function has to be called when domain is running. So my question is if there is an atomic way to test the domain's state and get its stats? Or, it's ok to call this function when domain is not active, but caller just gets error

My www directory is owned by "apache" and the group is "todd" and the permissions are 775. My Windows computers use Samba and they log into Linux with "todd". Under the www directory there are various directories which may have a group belonging to a user e.g. "viewpoint". Using this example, there is a directory under www (acutally called httpd),

Is there no way in which one can access the host's filesystem from within a guest OS. Libvirt's virt-manager GUI seems to indicate that there is, by virtue of the FileSystem Passthrough option as shown below [image: Inline image 1] The scenario I typically have is a Linux Server on a ext4 file system, with a Windows 7 Guest OS running a KVM machine. No matter what combination of

Hey, Over in KubeVirt we're investigating a use case where we'd like to perform a live migration within a network namespace that does not provide libvirtd with network access. In this scenario we would like to perform a live migration by proxying the migration through a unix socket to a process in another network namespace that does have network access. That external process would live

Hi all, I compiled a custom version of QEMU 2.0.0 and I am having hard times to make it available to libvirt. Just to clarify, if I execute /usr/local/bin/qemu-system-x86_64 it does performs good. But when I put this very same path to <emulator> tag in a domain configutation, when i start the domain I get error: Failed to start domain vm1 error: internal error: process exited while

I am using kvm libvirt/qemu, and am trying to get VNC working with unix sockets. I'm using the following in my XML: <graphics type='vnc' socket='/tmp/kvmtest'/> This works, it creates the unix socket and I can use it for VNC. But it creates the socket with 755 permissions, and owned by libvirt-qemu:kvm. Ideally, I would like it to be 770 root:libvirtd, but could also

Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look
