Prepare LibreOffice MSI to deploy with GPO

Posted on by Andy

The problem is that LibreOffice supports multiple languages when installing. So in order to deploy the MSI through GPO you need to set only one language:

  1. Download MSI package from www.libreoffice.org
  2. Download and install InstEd
  3. Open InstEd and then open the libreoffice msi
  4. Select Tables -> Summary Info
  5. Change the language field to 1033 (1033 is for english, adjust for other languages)
  6. Save the file and install it through GPO

Posted on by Andy

With this simple command your can convert raw img to qcow2: 

qemu-img convert -f raw -O qcow2 <source>.img <destination>.qcow2

and then edit your virtual domain XML file and replace type="img" with type="qcow2" and update the disk file name.

Done. 🙂

USB drive not recognised (error -71)

Posted on by Andy

CentOS 7 recently had an error when connecting a USB drive. I guess this came after updating to the latest kernel. The errors in dmesg or /var/log/messages were: 

[ 4159.607574] usb 1-1: new full speed USB device using uhci_hcd and address 4
[ 2079.875502] usb 1-1: device descriptor read/64, error -71

[ 4162.465330] usb 1-1: device not accepting address 7, error -71

After some googleing i found a fix for that: 

# vim /etc/modprobe.d/options.conf

and add following line to it: 

options usbcore use_both_schemes=y

more information about what this line does can be found here.
