[libvirt] [PATCH] libxl: Allow libxl to set NIC devid

Re: [libvirt] [libvirt-users] Not able to open Xen Connection using libvirt
by varun bhatnagar 21 Jun '13

21 Jun '13

No it was not booted with xen kernel. Actually I tried booting it with xen kernel but I am getting a message saying Error No 15 : File not found. I tried editing the grub entry and noticed that there are 3 entries: 1) kernel /boot/xen.gz vga= mode-0x345 2) module /boot/vmlinuz-3.0.13-0.27-xen....... 3) module /boot/initrd-3.0.13-0.27-xen And in /boot i listed down the files, only xen.gz is there. Rest of the 2 files are not there (pasted the screenshot below). Even at one site it was given to remove /boot from the path but that also din't work. How shall I solve this one? // Varun On Wed, Jun 19, 2013 at 1:07 AM, Prasad <prasad(a)mukhedkar.com> wrote: > On 06/18/2013 10:03 PM, varun bhatnagar wrote: > > Hi, > > I am trying to create virtual machine through libvirt using xen > hypervisor.
