I have RHEL 7 Beta installed in dual boot with CentOS 6.x. Since RHEL 7 installed GRUB2, I had problem that RHEL 7 is default boot. My personal solution was to go to /etc/grub.d and run command: mv 10_linux 31_linux grub2-mkconfig -o /boot/grub2/grub.cfg Explanation: - /etc/grub.d is where grub2 writes down config files used to create boot menu. - OS-prober creates 30_os-prober file in

Hello, I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted the Hypervisor and Dom0. The screen is always black after some kernel messages rapidly go by. I think that I may pass the wrong parameters to the kernel or Hypervisor with GRUB2. Can any one share his/her working grub.cfg for GRUB2 with

As of the latest updates to anaconda and grub2 for Fedora 18, it is now possible to install with /boot as a btrfs subvolume. The way that grub2 is handling this is the "reach down" to the files it needs as if the subvolume was a directory. Is this OK? At this point I am not worried about snapshots or any other complexities. If the subvolume name is known. should grub2 be able to

Confirmed this issue. To reproduce: Install a fresh Wheezy AMD64 guest under Xen 4.1 (hypervirtualized, boot from the debian-7.1.0-amd64-CD-1.iso). Use "entire disk" automatic layout for partitioning, this creates /dev/xvda1 for / and /dev/xvda5 for swap. It will create /boot/grub/grub.cfg with many references to (/dev/xvda,msdos1) which works fine when the machine is booted

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64 bit version using the tutorial at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/ on a Lenovo thinkcentre workstation. When I boot I get a kernel panic. If I boot the Linux kernel that I compiled using the

If I boot into CentOS on my home server from a Live CD or USB stick and go to Troubleshoot, it lists OS's it finds on the machine. How does it find these OS's? Presumably it looks through all the partitions on all the hard disks for something that looks like an OS? But how exactly does it identify an OS? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College,

Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14

I installed CentOS 7 on a Shuttle X27D box (dual-core Atom 330), and so far it seems to work fine, but it didn't set up a Grub2 entry for the existing Windows XP installation in the first partition (MBR). Running os-prober generates no output. fdisk shows that the NTFS partition is still present as /dev/sda1, and still has the bootable flag set. I added a menuentry for Windows to the end of

Hello Everyone, I have been trying to get a Fedora 12 domU to boot for the better part of the afternoon and haven't had success booting any F12 kernel in Xen. I can get Fedora 11 installed no problem, tried to do a preupgrade but the when booting the preupgrade kernel through grub (or even from outside the domU) the domU reboots very quickly and ultimately crashes. As far as I saw in the

Is there a way to get GRUB2 and the kernel to run a "serial" console under KVM? I'm running a Fedora 20 desktop, with libvirt-managed VMs. When I run a CentOS 6 VM, I can set both the boot loader and kernel up to use ttyS0 and get a console compatible with "virsh console". When I try the same with a CentOS 7 VM, it doesn't work. If I set it to ttyS0, I just

Hi I've reviewed and am performing some tests for the V6 to V7 preupgrade assistant. I have some suggestions for the wiki page. I have started a google doc with some suggested additions. They will most likely be added to as I discuss stuff with the dev mailing list. Whoever is responsible for maintaining the upgrade guide page on the wiki, could you give me some feedback please. Here's

Hi, I'm using libguestfs 1.42, When I run the following python3 commands on a rhel7.8: print(g.ls('/sys')) print(g.sh('ls /sys')) I get: [] block bus class dev devices firmware fs hypervisor kernel module power It seems that g.ls('/sys') is chrooted correctly. But g.sh('ls /sys') isn't. I came across this behavior when I used

Hello! Just thought I'd present this problem for comment/help/hints: * want to upgrade from Fedora Core 11 to 13 * I have a 64-bit system with Vista as a host o/s, running VMWare, and FC11 as a client o/s * cloned my FC11 as a backup * ran preupgrade, got expected problem with 200MB /boot, but preupgrade said that it could continue downloading (presumably to the larger partition) so I did
