How do I -
by Bob Goodwin
I have two drives in this computer, sda has Fedora 19 installed on it,
sdb has Fedora 10, both the dreaded LVM's!
What esoteric string of commands is required to permit access to the
Download directory on F-19 from F-20?
At this point I am considering re-installing both using a conventional
directory system such as I have just installed for Fedora 20 and Centos
6.5 on another computer ...
Any suggestions appreciated,
Bob

Fc20, systemd, and nonexistent services
by David Mehler
Hello,
I'm running a new FC20 system, one that was upgraded.
I'm using:
systemctl -t service -a -l
to check services and I'm seeing several that I don't have installed,
exim (MTA?) for example. I've tried using systemctl disable to remove
the service, and don't get anything back.
How do I prune my services list/get the unknown or uninstalled packages out?
Thanks.
Dave.

IOMMU issue
by Stephen Davies
I have just used fedup to upgrade from FC17 to FC18.
When I reboot into fedup, the screen is unreadable in graphics mode so I
changed the grub configuration to use console.
Now booting to fedup gives:
dmar:IOMMU: failed to map dmar0
and hangs/crashes/freezes.
If I reboot to FC17, the system is perfectly usable but dmesg tells me:

After a deal of Googling, I tried adding iommu=off to the grub configuration
boot args.
With that in place, neither FC17 nor fedup will boot so I have taken it out
again.
Any ideas as to what I can do to get fedup to boot?
Cheers and thanks,
Stephen Davies

recommendations on how to recover a corrupted, LVM-based hard drive?
by Robert P. J. Day
a friend asks me if there's a way to solve the following, not out of
any sense of urgency (since there are backups) but more out of a sense
of curiosity as to whether it can even be done.
long story short, a 750G drive which *used* to be the primary drive
in a laptop was replaced with a newer drive, and the older drive was
reassigned to be the secondary drive, /dev/sdb. in order to
occasionally copy stuff from the old home directory, this entry was
added to /etc/fstab on the new system:
/dev/vg1/home /opt/home ext4 defaults 1 2
so that (obviously) what used to be the "home" logical volume in the
old "vg1" volume group appeared under /opt/home, and was available for
the occasional restoration of old content.
problem: person was trying to write a 2G bootable (embedded Linux)
image to an inserted USB drive and, rather than writing to /dev/sdc
(the USB drive), "dd"ed to /dev/sdb instead, overwriting the first 2G
of the secondary hard drive and, with it, whatever LSM content resided
in that first 2G.
i have the drive connected to my fedora 20 laptop as /dev/sdb and,
sure enough:
$ sudo fdisk -l /dev/sdb
Disk /dev/sdb: 698.7 GiB, 750156374016 bytes, 1465149168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 * 2048 198655 98304 e W95 FAT16 (LBA)
/dev/sdb2 198656 3481599 1641472 83 Linux
$
so while the physical disk correctly shows up as almost 700G, the
partition table has been replaced by the one from the embedded image,
rendering the rest of the hard drive inaccessible.
is there any utility that will scan the drive beyond what is
referenced by the partition table and try to identify valid logical
volumes? i don't know anything offhand, so i'm open to suggestions.
thanks.

Focus-follows-mouse in KDE under FC19?
by William W. Austin
Apologies if this has been answered already but I didn't see this in
the archives and a web search didn't find anything more recent than
FC14 (and that trick didn't work under FC19)
Last week I upgraded my wife's linux box from FC17 to FC19. She uses
the KDE desktop.
Saturday she announced that she cannot live without focus-follows-
mouse.
Previously I would simply use /bin/systemsettings > Window Behavior >
Focus, and then select "focus follows mouse" - but that option has been
removed for some reason. So I spent much of the weekend trying to find
a way to restore the capability.
A friend suggested that I use gnome-tweak-tool to set Windows>Window
focus mode to "mouse." That didn't help so I tried "sloppy". Ditto -
no effect.
Is there anyway to turn this back on in FC 19 (or 20) for KDE?
Otherwise I'm going to have downgrade her machine back to FC 17 just to
keep peace at home.

Virt-Manager with MacVTap not working?
by John Obaterspok
Hello,
I've setup a VM with default networking (NAT) and this works fine but hosts
on my LAN can't get to the VM since it uses NAT.
When I try to set network to use MacVTap with either default or bridged I
get no networking for the VM.
Any hints around this? I would like to have the VM's on the same LAN as my
other machines. I don't care if the VM host can't reach the guests.
