[libvirt] libvirt 1.2.1 vs. Xen 4.1.4
Hi, a user of Debian's libvirt backport to wheezy using Xen reported libvirt 1.2.1 failing for him like: info : libvirt version: 1.2.1 error : virIdentityGetSystem:173 : Unable to lookup SELinux process context: Invalid argument error : xenHypervisorDoV2Sys:1011 : Unable to issue hypervisor ioctl 3166208: Permission denied error : xenHypervisorDoV2Sys:1011 : Unable to issue hypervisor ioctl 3166208: Permission denied error : xenHypervisorDoV2Sys:1011 : Unable to issue hypervisor ioctl 3166208: Permission denied error : xenHypervisorDoV2Sys:1011 : Unable to issue hypervisor ioctl 3166208: Permission denied error : xenHypervisorDoV2Sys:1011 : Unable to issue hypervisor ioctl 3166208: Permission denied error : xend_req:302 : internal error: failed to parse Xend response return code error : xend_req:302 : internal error: failed to parse Xend response return code error : virNetSocketReadWire:1454 : End of file while reading data: Input/output error It seems there weren't any significant changes in this code area recently so I wonder what might be triggering this? Since I currently don't have a xen test setup it'd be happy about any pointer. We don't have libxl enabled. https://bugzilla.redhat.com/show_bug.cgi?id=1055165 has a similar error message. Cheers, -- Guido

I was able to reproduce this with git master and Xen 4.1.6. The attached patch fixes it for me. Regards, Jim

Commit df36af58 broke parsing of http response from xend. The prior use of atoi() would happily parse e.g. a string containing "200 OK\r\n", whereas virStrToLong_i() will fail when called with a NULL end_ptr. Change the calls to virStrToLong_i() to provide a non-NULL end_ptr.
