QUESTION
I use Travis to run my JUnit tests on Android via the emulator. This works very well so far. However, how can I determine what the latest version of sdk-tools-linux-*.zip is? Currently, I am using version 4333796. Are there any dependencies between the SDK tools version and the Android SDK version or the build tools version?
...ANSWER
Answered 2021-Mar-08 at 01:24Easy!
The latest version will always be 4333796 because sdk-tools is deprecated. If you want to use the new approach, use commandlinetools-linux instead :)
QUESTION
I know from this answer that it's possible to spin up and run Vagrant Boxes on TravisCI using libvirt
instead of VirtualBox.
Is that also possible with GitHub Actions? Since we're moving everything away from TravisCI because of the new pricing model, we also need to switch our Vagrant-based test cases.
...ANSWER
Answered 2021-Feb-18 at 14:01Yes, this is possible using the macos-10.15
(which is currently the macos-latest
) environment. You could also try to go with macos-11.0
, but there currently seems to be no stable VirtualBox release for Big Sur. I created a small example project at https://github.com/jonashackt/vagrant-github-actions
Assume you have a Vagrantfile inside your repo like this:

Answered 2020-Dec-22 at 11:15Probably the cleanest object to construct from the output will be a map(list)
with the VMs as the keys and their list of IPs as the value. You can use a for expression like the following to construct this map:

QUESTION
Libvirt gives the definition of domain
, i.e. it is an instance of OS running in VM. But then virsh domcapabilities
reports the capabilities of this OS as well as underlying hypervisor
, so domain
definition is kind of blurred, it's on the boundary of virtualized OS and hypervisor?
ANSWER
Answered 2020-Dec-03 at 13:55A domain
in libvirt
jargon is a VM. In some other documents you can see the word guest as well. virsh domcapabilities
tells you can features can be used for the virtual machine on that hypervisor.
QUESTION
I have heard its a conventional practice to store program dependent files in /usr/share/application-folder
in linux. So I'm trying to do it in my c program in a function called load_interface_files()
for example. I am not sure if this is a good practice or not, I've heard about creating configuration files for this kind of issues.
Anyways, here's the the code I wrote to make a directory in /usr/share
.
ANSWER
Answered 2020-Dec-01 at 04:25use ls -ld /usr/share
to see what the permissions on the directory are (without -d
, you get the contents and their permissions).
Use code like:
QUESTION
I want to expand the disk capacity of the win7 virtual machine,but it prompts me that there are snapshots and cannot be expanded,but the snapshots cannot be deleted.
...ANSWER
Answered 2020-Nov-22 at 03:23Sometimes virsh and qemu see different things. This is occasionally because one of them is blind, and less frequently because one of them is hallucinating. In this case I believe virsh is blind. Try this:
QUESTION
After reading wiki libvirt I started virt-install
to install VM off the Debian10 netinstall ISO image:
ANSWER
Answered 2020-Nov-11 at 22:11I managed to proceed with installation only with graphics enabled, i.e. passing --graphics vnc,listen=0.0.0.0
to virt-install. This will start virt-viewer
(should be installed).
QUESTION
I have a Windows 10 Pro virtual machine using KVM. It is set up through virt-manager using the latest version of libvirt and QEMU. All of this is running on Manjaro Linux 20. Manjaro defaults to using PulseAudio for its audio output (at least for Manjaro 20). I was wondering if there is a way to use PulseAudio with libvirt/QEMU/KVM to have an audio pass-through from the guest OS to the host. Meaning that anything that is playing in the Guest OS will need to be heard through the default output device in Manjaro Linux. First, I tried setting environment variables to set it up, but that didn't work, and it also is deprecated past QEMU 4.1 (I am using 5.1.) Then, I tried using this tutorial, which ended up somehow bricking Manjaro, and I had to reinstall. I am currently using the default Spice server through virt-manager. I have heard that the Spice server introduces lots of overhead, and I can't afford that. I need every CPU cycle, and if PulseAudio is already running, I may as well use it. My libvirt XML config WITHOUT the Spice server is as follows:

Answered 2020-Oct-28 at 19:08This is more of a comment, really...
I don't use libvirt
myself, but as far as I can tell there aren't any audio devices in your config.
Here are the qemu
command line options I use for guest (Win10 and others) audio output to PulseAudio output on -machine q35
