Switch to BLS failed
by GianPiero Puccioni
Hi,
I have a machine with F29 and a partition with an old WinXP (not EFI).
Before updating to F30 I wanted to try the new BLS so I used
"grub2-switch-to-blscfg" to test the transition, but something went wrong.
Before I did a full update and reboot to be sure, but after I gave the command
and rebooted the start menu showed only "Win Xp" no linux start.
Looking around I found a few things to test but nothing worked.
in "grub>" the command blscfg gave "can't find command 'blscfg'"
but /boot/loader/entries/ was populated with 4 .conf entries.
Only way to start Linux was the command "configfile /boot/grub2/grub.cfg.bak"
and I was able to go back to "standard" (edit "/etc/default/grub"
set "GRUB_ENABLE_BLSCFG=false" and rerun "grub2-install /dev/sda" and
"grub2-mkconfig -o grub.cfg").
Has anyone tried this? Did I miss a step or something?
Now that I know how to get back, and I saved a "good" grub.cfg, I can try
again.
Thanks,
G

F30 LVM partition on a notebook
by Robert Moskowitz
I decided to use the default partitioining options on the install and I
see that swap and the ext4 /home are in a LVM partition.
What does LVM buy me on a notebook? It is not like I am going to add
another drive and extend /home onto it.
In fact if I have to pull the drivew to rescue data from /home, I then
have to contend dealing with LVM and what if it is the same label as the
lvm on the system I try to mount it on.
Seems to me, in my limited knowledge, that I should continue as I have
for some time and just create the swap and home partitions directly.

F30 QEMU migration of a F21 image failed to start
by Robert Moskowitz
First I installed QEMU on F30:
dnf groupinstall "virtualization"
dnf install qemu virt-manager libvirt
systemctl enable libvirtd
systemctl start libvirtd
systemctl enable libvirt-guests
systemctl start libvirt-guests
I backed up my fedora21.qcow2 from my old F28 system and then copied it
to the new F30 system. The target directory on each system is:
/var/lib/libvirt/images
I started QEMU, then went through the steps of migrating an image. This
worked with this F21 image from F21 to F24 and again to F28. This image
has some restricted content data that I work with in this manner.
This time, with F30, the migration failed and kept looping based on what
I saw in the QEMU session via a <Alt-D>.
Anyone working with QEMU with EOL Fedora images?

router usb port problem
by AV
I have a linksys e3200 router and 3 pc's connected:
fed30 desktop, fed30 laptop & Imac with latest macos Mojave.
All connections are ethernet (I don't like wireless).
I also have an Epson inkjet connected by usb cable to Imac.
I can print from Imac: usb + wireless(if I configure wireless)
I can print from desktop: usb (but too much bother switching
cable from Imac to desktop)
I can print from laptop: usb + wireless(if I configure wireless)
The desktop does not have wireless card so can't use that.
(Wireless printing is directly from pc to printer, not via router)
Now the linksys e3200 has a usb port that should be able to handle
compatible disks and printers. If I could could configure this
for the printer I would be able to print from all 3 pc's
without problems as the printer is in the local network.
The problem is I can't get this to work.
First I don't even know if the port is active (i.e. if it works).
I don't have a compatible disk to try if it works with storage.
(It certainly doesn't work with usb sticks).
If I "configure" printing (ipp) with cups after installing Epson
driver I cannot print ("no connection" to printer).
It (an IP address) does not show up in anything I try
(nmap only shows the router and the pc IP's for example).
A check should be able using the 'Cisco connect' software
on the Imac. But the latest version is not accepted by Mojave
even though it should be compatible, so I cannot install it.
Is there any way of finding out if the usb port is working?
If not I will have to buy a wireless dongle for the desktop
and use wireless (even though I would prefer not to).

Question regarding bash scripting
by sixpack13
hallo
I usallay run vanilla kernels and build them with a suffix "_MY" to save some works when cleaning /boot if that kernels gets outdated and a new one gets installed.
/boot looks like this
ll /boot :
...
-rw-------. 1 root root 20M 22. Jun 15:04 initramfs-5.1.14_MY.img
-rw-r--r--. 1 root root 4,7M 22. Jun 15:04 System.map-5.1.14_MY
-rw-r--r--. 1 root root 15M 22. Jun 15:04 vmlinuz-5.1.14_MY
...
and
ll /boot/loader/ :
drwx------. 2 root root 4,0K 22. Jun 15:04 entries
and
sudo ls -l /boot/loader/entries/ :
-rw-r--r--. 1 root root 242 22. Jun 15:04 0637b2e09df64d90bd0c13dc10d1da70-5.1.14_MY.conf
to clean /boot a use a script:
#!/bin/bash
set -vx;
sudo rm -rf /boot/loader/entries/*MY*;
sudo rm -rf /boot/*MY* /lib/modules/*MY*;
sudo grub2-mkconfig -o /boot/grub2/grub.cfg;
and now my problem:
the first sudo rm -rfv command does NOTHING, means the loader entry is still there and I need to rm it by hand.
whereas the second rm command does what I espect.
What I'm doing wrong / where is the/my bug ?

F30 - No irq handler for vector
by Robert Moskowitz
Lenovo x140e:
At boot up time I see the following messages appear briefly.
Jun 25 09:03:44 lx140e kernel: do_IRQ: 1.55 No irq handler for vector
Jun 25 09:03:44 lx140e kernel: do_IRQ: 2.55 No irq handler for vector
Jun 25 09:03:44 lx140e kernel: do_IRQ: 3.55 No irq handler for vector
Note that the system is not 'seeing' my wifi adapter.
Also I would see one "No irq handler for vector" with F28 on my old
Lenovo x120e.
