...n-detect is not installed by default on most Xen systems, and dracut uses xen-detect to decide whether to include the module. It also has some problems: 1) it does not try loading xen_platform_pci; 2) it loads modules unnecessarily; modules.alias is where all Xen support should reside. Assuming xenbus_probe_frontend and xen_platform_pci are loaded so that Xen devices are probed, other modules are picked up automatically thanks to aliases such as alias xen:vbd xen_blkfront 3) Even not-so-recent kernels (say 2.6.32) require the xen_platform_pci and xenbus_probe_frontend modules even for non-paravirtualized...

Hi, The following patch series fixes hangup after creating checkpoint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux

I am running Xen 4 and want users to be able to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s
