Hi! I''m experimenting with Xen 4 on Squeeze. Squeeze uses grub2 by default, and the config format has changed. I can''t for the life of me figure out where to set options for the hypervisor and the Dom0 kernel on bootup. It seems the grub2 stanza for xen is being generated by /etc/grub.d/20_linux_xen and that seems to have some provisions for receiving arguments, but I

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Hi All - I have my 40_custom file setup. What is a good way to make that the default boot option ? I'd rather not count menu option lines and change GRUB_DEFAULT to that - as I am doing this remote. Thanks Jerry

...me after bootup. Since we run all our systems with efi network boot as the first boot option for rescue operation, this would be a significant problem for the future if the behavior cannot be turned off. I have already checked the use of efibootmgr and some of the related grub settings such as GRUB_DEFAULT and GRUB_SAVEDEFAULT (which may have nothing to do with it). On Debian, I found a debconf option that prevents updating nvram. This seems to prevent the described behavior. Does anyone have an idea for this problem? With kind regards Florian

I have a couple Debian 6 HVM VMs. From what I''ve read, Debian 6''s standard kernels have pv_ops already enabled. I''d like to convert these to pv for the following reasons (Assuming both of are valid expectations): 1) so the VMs use pv for the NICs 2) so the VMs properly respond to shutdown/reboot commands from xm I''m having trouble converting them. I believe
