Error when trying to reboot a VM in Proxmox

I have a stable proxmox environment. After a while, when I try to reboot or shut down a vm, it gives me the following error: 

starting worker failed: unable to parse worker upid 'UPID:fsm-05:0005E6C2:13CC0EA5A:539EB0E9:qmshutdown:109:root@pam:'

If I try to take same action from console with command 'qm 109 stop', I face with same error. After some research, I have found a solution to save the day. It seems that somehow regex doesn't match to a UPID. If the regex is redesigned, problem will be solved.

Two files need to be edited. Back up following files and do necessary edit on them as shown below:

On /usr/share/perl5/PVE/Tools.pm:

Replace:

if ($upid =~ m/^UPID:([a-zA-Z0-9]([a-zA-Z0-9\-]*[a-zA-Z0-9])?):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8}):([^:\s]+):([^:\s]*):([^:\s]+):$/) {
With:

if ($upid =~  m/^UPID:([a-zA-Z0-9]([a-zA-Z0-9\-]*[a-zA-Z0-9])?):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8,9}):([0-9A-Fa-f]{8}):([^:\s]+):([^:\s]*):([^:\s]+):$/)  {

On /usr/share/pve-manager/ext4/pvemanagerlib.js:

Replace:

var res = upid.match(/^UPID:(\S+):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8}):([^:\s]+):([^:\s]*):([^:\s]+):$/);
With:

var res =  upid.match(/^UPID:(\S+):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8}):([0-9A-Fa-f]{8,9}):([^:\s]+):([^:\s]*):([^:\s]+):$/);

After saving both files, restart pvedaemon. You should be able to restart VMs.

My environment is Proxmox2.3 on Debian7.0.  This may have been solved in the latest version. So upgrading may be a solution too. But it is always a good practice to do an upgrade on working environment. This is where our solution is needed.

    And mine! Couldn't open a console into my machines.

    Restarted pve deamon with service pvedaemon restart

Integration of MuPDF Project as a Library into an Android Studio Project

I have needed to use MuPDF library in my android project. After some research, I have seen that there are many integration tutorials but, but integrated projects are developed on Eclipse. For projects on AndroidStudio+Gradle, there is no example. I mean there is no specific example which exactly refers to this issue. So, after achieving my goal, I want to share the steps publicly so that it can be reused by others.

A Way To Monetize Your Kivy Game

While I am building my game, I look for a way to monetize it. This will be my first game, so it is also the first to attempt earning money with an App. I am also not familiar to monetization companies. So, I have done a search to find an appropriate ads network which can be easily integrated with kivy . The first and only company who provides a sdk for kivy is RevMob . I integrated RevMob sdk and tested it. Unfortunately, it doesn't have a good performance and FullScreen Ads crashes. Just links will work. Therefore, RevMob option is not really preferable since ads need to be visually effective. You can also integrate android sdk of any ads network by using pyjnius . In this post, I will show how to use Adbuddiz sdk with kivy.

Encoding multi-dimensional value into 1-D with preserving closeness

After a very long time, this will be my first post. I hope that it will not be the last, and the rest will come. For a project about taxi trajectory prediction, I have applied k-NN algorithm on coordinate sequence of taxi trips. Did I have promising results? Well, it is arguable, but I have discovered some good techniques. One of them is Z-order curve (Figure 1). Figure 1: Four levels of Z-ordering (taken from Wikipedia  page) I was looking for a technique to decrease dimensionality of 2-D coordinate representation (lat-lon) into 1-D . But on this 1-D value, I would like to apply k-NN algorithm. For this purpose, 1-D values must preserve the closeness of two different coordinates. If I do linear ordering of latitude and longitude values, I couldn't achieve this goal, because closeness will depend on only one value which is placed on the right-most. Let's assume I do linear ordering as lat-lon:
