Hi, I''m the Mageia XEN packager and during QA, we stumbled into a problem. in fact, we wanted to test Mageia 3 installation on a HVM. so, we had a sparse image and a iso file: [ ''file:/opt/testhvm.img,sda,w'', ''file:/opt/mageialive.iso,hdb:cdrom,r'' ] the live booted, and was able to install to disk, but it never seemed to boot after the install...

...e a Xen DomU PV, so you can either upgrade to the CentOS Plus kernel in PV mode .. or you can shift your DomU to either HVM or PVHVM modes.? PVHVM is more like PV mode, and is usually much better than HVM mode. More info on PVHVM here: https://wiki.xen.org/wiki/PV_on_HVM https://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers The anaconda installer and pxe booting from the standard tree 7.4.1708 tree will also not work in PV mode for new installs, only PVHVM or HVM installs can be done with the 7.4.1708 tree. Note:? This is an upstream source code issue and will not be fixed in the main CentOS Linux 7 kernel unless it...

Use "firmware_override" instead if you really want a non-default firmware WARNING: ignoring device_model directive. WARNING: Use "device_model_override" instead if you really want a...
