failed anytime at the final step.
[root cause:]
the root cause is the xattr setting on /etc/resolv.conf
I was using pppoe connection last days, and setting /etc/resolv.conf with a fixed value.
cisco anyconnect will try anyway to replace/update items in /etc/resolv.conf. failed if no update permission.
I used “chattr +i ” to keep the file stable, but it failed to update and cisco anyconnect will give up connection at last.
[solution]
chattr -i /etc/resolv.conf
After migrating my VMs onto new hosts. failed to restart VM box
“on the Network: Adapter 1 page , no host-only network adapter is selected”
Solved:
–>”You can add new adapter at File – Preferences – Network.”
Quote:
OS: Fedora 15.
Well this os is currently out of support and, which was shipped as experimental on systemd.
I can see following messages in /var/log/message and system cannot access X.

Actually nothing helpful is found. but the msg:”Not a directory”
after a few checks… I found the path “/usr/lib/systemd/system/” is removed, just a file “/usr/lib/systemd/system” there.
the fix is to change the file backto an empty folder.
###
well about F15, this folder itself is empty but, it should not be removed
otherwise, you cannot see the login session/window.
Following is a step to install Mongo-php-driver and rockmongo on EL5.6 box.
steps please find the reference.
My working configure:
php-devel-5.1.6-39.el5_8
mongo-php-driver: mongo-1.2.0
rockmongo-1.1.5
httpd-2.2.3-65.0.1.el5_8.3
1. install the pkgs.

2. git install mongo-php-driver. as the git repo is up2date and the box is old.
I choose to pickup the driver pkg here:
http://pecl.php.net/get/mongo-1.2.0.tgz
install the mongo.so library.
3. edit php.conf and enable the mongo.so as extension.
4. during httpd start. hit bug#669963
httpd server cannot startup and report error in /var/log/httpd/error_log
