I gave the virtx7-44-testing packages a spin on a fresh CentOS 7 install (legacy boot, no efi, as there is no xen.efi). However, I was not able to start any HVM or PVHVM guests. Upon create, the DomU was setup but did not do anything, but instead entered a reboot-loop (Dom ID was increased, but no boot output. No bootloader output on the console, despite everything in the guest setup to display on serial console). The exact same guests worked fine with Xen4CentOS xen+kernel packages for CentOS6. Note, that PV DomUs run fine (tested with CentOS5). I did not invest too much time into debugging, but from xl's logs, the DomU was apparently shutdown upon creation: Waiting for domain xencen7 (domid 1) to die [pid 3162] Domain 1 has shut down, reason code 1 0x1 Action for shutdown reason code 1 is restart Domain 1 needs to be cleaned up: destroying the domain Done. Rebooting now Waiting for domain xencen7 (domid 2) to die [pid 3162] Domain 2 has shut down, reason code 1 0x1 Action for shutdown reason code 1 is restart Domain 2 needs to be cleaned up: destroying the domain Done. Rebooting now .... The interesting part is, that the pid of the xl create job (3162) remains the same, thus xl create never exits but instead attempt the re-create the DomU in a loop, only to be stopped by killing the xl process. At the moment, I run my own self-build CentOS 7 xen packages. But if desired, I can switch back to the virt7-xen-44-testing packages to assist any debugging. Regards, Thomas
