similar to: Hello and a question about QEMU log

Hello, I have a custom QEMU which requires some non-standard command line arguments to launch a VM. e.g., "--proc-type=secondary" option is always required to launch a QEMU VM. To launch the VM through libvirt (virsh) "How do I specify these non-standard options in XML? OR if thats not possible ,Can you guide me at which point (code file) libvirt converts the XML to QEMU command

Hello all, So I am trying to get a qemu guest to use a custom patched seabios image rather than the default /usr/share/qemu/bios.bin I have tried changing the domain config file to include either: <os> --SNIP-- <loader readonly='yes' type='rom'>/home/telemin/qemu/seabios_patched.bin</loader> </os> OR domain type='kvm'

Dell Customer Communication Hi All, I am using Compiled against library: libvirt 1.2.9 Using library: libvirt 1.2.9 Using API: QEMU 1.2.9 Running hypervisor: QEMU 2.1.2 I want user to provide username and password authentication to virConnectPtr virConnectOpenAuth(const char *name, virConnectAuthPtr auth, unsigned int flags) to login remotely for the qemu

Hi libvirt-user, If I run (as a normal user): virsh -c qemu:///session net-list --all virsh -c qemu:///session pool-list --all I see a default network and a default pool. And indeed, these appear in the persistent configuration. It seems these are created the first time libvirtd is (auto)started in qemu:///session mode. Is it possible to configure the attributes of the default network and

Hi Daniel, I changed the libvirt code to support "-net dump" because it is more comfortable to me and to users here. I don't know if it is interesting to the community, but... most of the code is ready if someone needs. Julio Cesar Faracco 2016-05-05 10:34 GMT-03:00 Daniel P.

Hi all, I have been trying to set cpu_exclusive flag. Now I can do it using "echo". I want to know is there any other way (an API) to set this flag? Is it possible to set this flag using API? Thanks.   ~Peeyush Gupta

Hey guys, I'm so glad you added the new set of virConnectListAllDomains functions, it simplifies a lot our work!. I was only wondering why there is no support for PowerVM. Is it that it hasn't been developed or is there some technical hardship? Best, Camilo Aguilar

Hi, I am using libvirt and virsh to create my VM on KVM. It works fine. However, I need to turn off vnet_hdr for virtio interface. Does anyone know how to do it through libvirt? Thanks.

Hi, What is the difference between chroot & pivot_root. They don't seem obvious based on the man pages apart from the below mentioned caveats. 1) Inherited Open file descriptors, have to be explicitly closed. 2) Does not change CWD of the process, which can be overcome by doing a chdir before & after chroot call. Any information on this would be useful. Thanks,

There are a couple of problems with passthrough qemu: 1. virsh version/capabilities command executes "qemu -help" but this gives an error in my case because my customized qemu has to receive mandatory non-standard parameters "qemu -c -n -- -help". 2. Similarly when passing arguments as passthrough in a VMs XML. How can I make sure that these non-standard arguments are passed

Hi Daniel, Thanks. The debugger program I used is a multi-level debugging tool called StackDB developed in our department. It was developed for Xen initially, and KVM support was only added recently. I've forwarded your email to the developer and hopefully it should be pretty straightforward to do so. Best Regards, Min On Nov 11, 2014, at 2:32 AM, Daniel P. Berrange

Hi there I’m not quite proficient with libvirt yet, and have been using it so far primarily to manage lxc containers I was hoping to find a means to configure the set of capabilities that guests should drop, but came across a few web pages suggesting these were set in stone in the code is this correct, or is there a means to tweak this set from the host via the xml config or a virsh command ?

How can I run command in containers on the host? Just like the lxc command lxc-attach. I run : virsh -c lxc:/// lxc-enter-namespace fedora2 --noseclabel /bin/ls but get error: libvirt: error : Expected at least one file descriptor error: internal error: Child process (14930) unexpected exit status 125 Here is my libvirt.xml <domain type='lxc'> <name>fedora2</name>

Hello! I am currently experimenting a bit with some of the LXC support under libvirt, and in trying to utilize the tool virt-login-shell, I encounter the following error: [james@lxchost ~]$ virt-login-shell libvirt: error : argument unsupported: Security model none cannot be entered Though it should be apparent from the lack of error, the domain is most definitely running.

Hi guys, Does anybody know how to dump the network trafic from each virtual machine using libvirt? Here, we usually use VPN softwares and other network tools inside Virtual Machines (Windows and Linux). Sometimes, this applications does not work properly, so we need to dump the network traffic of each Virtual Machine to compare and debug. How can I enable it using libvirt? I know that if you
