I wonder if there would be anyone who would be willing to add extlinux support to RedHat's grubby program. From the looks of it, they already have grub, lilo, zipl, elilo, yaboot, and silo support, so I can't imagine it's that complex. -hpa

When using grubby to get the default kernel of a guest, do not fail with a bogus error like: virt-v2v: error: libguestfs error: statns: statns_stub: path must start with a / character in case there is no default kernel that can be determined (e.g. because of a bogus configuration). --- v2v/linux_bootloaders.ml |...

I am looking at using grubby. My command is: grubby --grub --title "CentOS (2.6.32.60)" --add-kernel=/boot/vmlinuz-2.6.32.60 --initrd=/boot/initrd-2.6.32.60.img --args="ro root=LABEL=/ noapic" --make-default my etc/grub.conf file after running the command is: title CentOS (2.6.32.60) kernel /boot/v...

Detect only once which method must be used to get and set the default Grub2 kernel in the guest: this avoids the same checks in list_kernels and set_default_kernel. Also, add a "no method" option as well: Debian/Ubuntu guests do not have neither grubby nor Perl's Bootloader::Tools, so there is no way to know what is the default kernel, nor to change it. In this case, add a warning about this situation. --- v2v/linux_bootloaders.ml | 61 ++++++++++++++++++++++++++++++++++-------------- 1 file changed, 44 insertions(+), 17 deletions(-) diff...

Hi, this series adds a couple bits more in v2v to convert Debian/Ubuntu (and derived) guests. The series does not complete the support (see known issues below), but all the patches here should be fit for review and inclusion. The series does not enable the conversion, yet. Known issues: * currently tested with simple local guest images, hence needs testing with real guests on

...l my other servers contain). So I mounted /boot, and the the grub.conf file was not consistent: it did not have a stanza for the kernel I wanted installed. So I did a "yum remove kernel ; yum install -y kernel". Both the remove and the install resulted in this message getting printed: grubby fatal error: unable to find a suitable template Just for kicks, I renamed both the /etc/grub.conf symlink as well as the actual /boot/grub/grub.conf file, and repeated the kernel remove/install. This did NOT produce the above error; however, no symlink or actual grub.conf file was created. I did...

I ran "yum update" the other day on my dom0 and let it pull a new kernel. The RPM install scriptlet runs /sbin/new-kernel-pkg (part of the grubby package) to update grub.conf. It writes a new record to boot the Linux kernel instead of Xen. It would be nice if it noticed that it was running inside Xen and wrote a suitable record for that.

I think i might have solve it. For some reason grub2-mkconfig doesnt work. (Have no idea why) I manage to solve it with grubby. sudo grubby --args="intel_iommu=on" --update-kernel=ALL For some reason it works. I dont know if it works if my kernel gets upgraded.

When installing kernel-2.6.18-128.el5 in a guest with kernel-xen-2.6.18-164.el5xen already installed, and 'root=LABEL=/' on the kernel command line, grubby fails to install a grub entry for the new kernel. It only fails when run under libguestfs. Installing in the original Xen guest works fine. The underlying cause appears to be related to blkid, although I haven't managed to pin it down exactly. This change works around the issue. If virt-v2v en...

It turns out augeas on RHEL6 is 0.7.2, which does not have ''setm'' command available. ''setm'' is available in augeas release 0.8, which is available in EPEL, but not available for RHEL6 (the reason is the package is already in RHEL6, thus no package would be released in EPEL for this. All I want to do is to put console=ttyS0 on all kernel lines in /etc/grub.conf.
