I am trying to run StackVM. I am running Ubuntu 10.04 LTS in a VirtualBox. I have installed all the prerequisites for running StackVM as listed here. AQemu and other qemu packages are also installed.
I have added one simple linux image (linux-0.2.img) which is available on qemu's site
When I open stackvm in a browser and try to run the added simple linux image I get the following error on the terminal and nothing happens on the browser.
firing up qemu on localhost:5900
{ user: { name: 'foo' }
, disk: { name: 'simple linux' }
, file: 'linux-0.2.img'
, engine: 'qemu'
}
qemu on localhost:5900 died
Can anyone help me to get it running.

I'm trying to use the Intel NCS 2 on my Ubuntu 20.04 machine.
After configuring all the steps, I tried to run one of the examples:
/opt/intel/openvino_2021/install_dependencies$ ./demo_security_barrier_camera.sh -d MYRIAD
The first time the example worked. When I tried to run it again, I got the message
E: [ncAPI] [ 150951] [security_barrie] ncDeviceOpen:1017 Failed to find booted device after boot
Since then, I could not run the examples anymore. I tried to unplug/replug the device, reboot the computer, etc., but nothing.
I tried to search on internet concerning the error ncDeviceOpen:1017, but I got nothing.
Also, most of the topics I have found refers to Ubuntu imstalled on a virtual machine. I'm using Ubuntu 20.04 installed natively on my machine.
The Intel NCS is definitely recognized. In fact, lsusb gives me:
...
Bus 001 Device 017: ID 03e7:2485 Intel Movidius MyriadX

I'm new to podman, and I just trying to run containers on it.
(podman version 3.4.0, installed by brew, intel Core MAC)
However, when I trying to run "podman run {image-name}", below errors were thrown.
$ podman run -ti -d --name web httpd 125
Error: error configuring network namespace for container b0e70d672cb66005833c0a300c8661b88eab49e942c240d69d17587e0b75c47b: error adding pod web_2_web_2 to CNI network "podman": unexpected end of JSON input
$ podman run centos:7

By reading https://issueexplorer.com/issue/containers/podman/11452, I removed ~/.docker/, but the solution doesn't work in my case.
Of course, the error message says there was "unexpected end of JSON input", but I don't know how to fix it. Could anyone guess why podman didn't work even running these base images, or how to debug it?
Thanks in advance.
on macos, current machine version 3.3.1 has this problem. I had this problem on server version 3.3.1 and I do not encounter it on server version 3.4.0. You can check server version with podman version.
Try removing current machine and installing a newer one
podman machine stop
podman machine rm
podman machine init --image-path next
podman machine start
Check server version again with podman version.
Try running your image again.
I used to get frequent chrome driver error in karate UI tests. I have been using karate tests in VS code for the past 5 months. Now, I used to get driver config / start failed: chrome server returned empty list from http://localhost:[port] frequently. Sometimes, I need to run 20 times to run the same test to succeed. All other runs throws either "driver config / start failed: chrome server returned empty list" / "ERROR com.intuit.karate - evaluation of 'karate-config.js' failed: javascript function call failed"
I have installed chrome multiple times but I get the same error. Also I have re-imaged my laptop due this issue and through something went wrong. Even now I used to get the above errors often.
I have installed Chrome 64 bit in windows laptop, it get installed in "C:\Program Files\Google\Chrome\Application\chrome.exe" but karate standalone will always check the Chrome path "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" in runtime which doesn't exists.
Note: I have set the chrome.exe installed path in my system environment PATH but karate not considering the path variable. Please advise me on this.
So I have modified the driver config as given below:-
* configure driver = { type: 'chrome', headless: true }
[To]
* configure driver = { type: 'chrome', executable: 'C:/Program Files/Google/Chrome/Application/chrome.exe', headless: true }
Karate version: 0.9.6.RC3
OS : Windows 10 Home
JDK Version
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)

Chrome Driver config
configure driver = { type: 'chrome', executable: 'C:/Program Files/Google/Chrome/Application/chrome.exe', headless: true }

Please guide me how to resolve this issue.
Thanks,

I was same error. Actually its finding chrome.exe in different location where actually its not located.
In default it's looking at "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"
but actual path was 'C:/Users/ues/AppData/Local/Google/Chrome/Application/chrome.exe'
So check your chrome.exe path.
Hope it's helpful.
I have solved my problem by defining in the config file as;
"karate.configure('driver', { type: 'chrome', port: 9222,
executable: 'C://Program Files//Google//Chrome//Application//chrome.exe' });"
maybe assigning a port help me to solve the issue but one thing to consider here is that u need to use forward slashes in the executable command.
No one else has reported this, so you'll need to figure this out maybe with the help of someone who can troubleshoot your machine. Maybe there are some permission restrictions. Maybe your old processes are still running, so make sure you go to your task manager and kill them etc, this is quite common on Windows.
And please upgrade to 1.0 before trying anything else, because that may help: https://github.com/intuit/karate/wiki/1.0-upgrade-guide
Otherwise we will need your help to maybe debug and suggest changes to the framework. Ideally you should contribute code to Karate, and remember - it is an open source project. If you are able to replicate your problems, follow this process: https://github.com/intuit/karate/wiki/How-to-Submit-an-Issue - but I'm not sure that is possible with the kinds of issues you are describing.
If none of the above options work, you may need to consider switching to some other framework.
EDIT: most teams run on CI + Docker which is much more stable: https://stackoverflow.com/a/62325328/143475
I have KVM virtual machine running CentOS 7 as guest OS. I'm trying to attach an additional disk to it on the run (without shutting it down) using this command:
$ sudo virsh attach-disk centos --source /var/lib/libvirt/images/newdisk.img --target sdb --persistent
But receive an error:
error: Failed to attach disk
error: internal error: cannot update AppArmor profile 'libvirt-d2e7bbb8-c7b3-44ec-b0ea-27539e0df732'
If I do the same with Debian guest - everything is ok.
What is difference, how to solve that?
UPDATE:
I have a comment!
I compared two VM's xml and saw that CentOS have QEMU-agent in his configuration:
<channel type="unix">
<source mode="bind" path="/var/lib/libvirt/qemu/channel/target/centos_auto.org.qemu.guest_agent.0"></source>
<target name="org.qemu.guest_agent.0" type="virtio"></target>
<address bus="0" controller="0" port="1" type="virtio-serial"></address>
</channel>
Then I removed "channel qemu-ga", restarted VM and checked "hot add" feature. It worked.
I tested it on other VMs (CentOS, Fedora, Debian) and saw the same.
As a result:
If enable qemu-agent i cannot use hot plug.
If use "hot plug" i must forget about agent.
Is it my mistake in configuration or these features can't work together?
Host-OS: Ubuntu 15.10
QEMU emulator: now 2.4.92 (tested 2.3 and 2.4.1)
VMM: 1.3.0
This is a clear bug in the apparmor security driver for libvirt. The existence of the QEMU guest agent config in the XML should have no impact on ability to hotplug disks to a guest. This bug should be reported to the libvirt upstream, or Ubuntu bug trackers.
My libgdx app starts up on ios simulator and shows ios intro libgdx pic, then crashes.
I get:

Seems to be related to trying to run 64bit on iPhone 4s, where it is not supported. Does anyone know how to turn off 64bit for robovm in libgdx?
If I change the ios-sim command:
/Users/macuser/Documents/workspace/.metadata/.plugins/org.robovm.eclipse.ui/robovm-1.4.0/bin/ios-sim launch /Users/macuser/Documents/workspace/.metadata/.plugins/org.robovm.eclipse.ui/build/myapp-ios/myapp-ios/ios/x86_64/IOSLauncher.app --timeout 90 --unbuffered --devicetypeid "com.apple.CoreSimulator.SimDeviceType.iPhone-4s, 8.0" --stdout /var/folders/ml/zdhkbw3x0g9550pq9mgfrcsw0000gn/T/robovm-stdout-6250612031367207111.fifo --stderr /var/folders/ml/zdhkbw3x0g9550pq9mgfrcsw0000gn/T/robovm-stderr-5592986297298678222.fifo --setenv ROBOVM_LAUNCH_MODE=release --args -rvm:log=warn
To:
/Users/macuser/Documents/workspace/.metadata/.plugins/org.robovm.eclipse.ui/robovm-1.4.0/bin/ios-sim launch /Users/macuser/Documents/workspace/.metadata/.plugins/org.robovm.eclipse.ui/build/myapp-ios/myapp-ios/ios/x86/IOSLauncher.app --timeout 90 --unbuffered --devicetypeid "com.apple.CoreSimulator.SimDeviceType.iPhone-4s, 8.0" --stdout /var/folders/ml/zdhkbw3x0g9550pq9mgfrcsw0000gn/T/robovm-stdout-6250612031367207111.fifo --stderr /var/folders/ml/zdhkbw3x0g9550pq9mgfrcsw0000gn/T/robovm-stderr-5592986297298678222.fifo --setenv ROBOVM_LAUNCH_MODE=release --args -rvm:log=warn
It works with the old robovm. But for the new version it seems those directories aren't even built at all, so it fails.
Where should I specify the architecture? There is:
<arch>thumbv7</arch>
in robovm.xml but it doesn't seem to do anything?
Has this anything to do with the eclipse integration plugin (I am running from eclipse)?
OK I found out (after about 12 hours of digging)!
I looked in the wrong place all the time. The solution is (in eclipse) to go to Run Configurations / iOS Simulator App / Choose a device and select 32-bit (x86).
