...HVM guest not being able to resume propely b/c of hitting: 142 BUG_ON(info->type != IRQT_UNBOUND && info->type != type); (in events.c) and also adds a WARN to catch situations like these. The reason for this is that the Xen python toolstack does not setup HVM_PARAM_CONSOLE_EVTCHN parameter, so we would use the default value (0).. and ended up using the same IRQ line as the xen-platform-pci driver. Huh? Note: the ''xl'' toolstack _does_ set it. The reason is that the when the xen-platform-pci starts, it requests an PIRQ, and the info structure in events.c is...

This issue has been posted before, but no clear solution, i am sending again. 2.6.32 pvops dom0 booted with xen 4.0. However the xend can not start. I believe that is something related to the *evtchn*. I compile the CONFIG_XEN_DEV_EVTCHN=y in kernel, so i donot need to load it. When the dom0 booted, I can see there is a entry for evtchn in /dev/xen along with gntdev. But when xend starts, the evtchn in /dev/xen disappeared. and xend is not properly started. The error log in /var/log/xen/xend.l...

Hello folks I see the EVTCHN driver being initialized as a part of DomainU. XEND (or domain controller) uses the EVTCHN driver to receive notifications for events on the control interface. However there is no XEND (or domain controller) that runs in DomainU. So what is the purpose of initializing EVTCHN driver in DomainU T...
