Fix: Default EInstellung in der VM Konfig. für Paravirtualisation auf „default“ setzen

Älteren Kernel booten

/etc/default/grub

# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=saved GRUB_SAVEDEFAULT=true GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT=_ckgedit_QUOTckgedit> GRUB_CMDLINE_LINUX=_ckgedit_QUOTckgedit>


Default Wert ist GRUB_DEFAULT=0

REDIS Server

Nach do-release-upgrade fehlt der REDIS Server. Neu installieren gemäss https://www.techandme.se/install-redis-cache-on-ubuntu-server-with-php-7-and-owncloud/ und https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-redis-on-ubuntu-16-04

Shorewall

Nach dem Update startet Shorewall 5.x nicht mehr automatisch beim Boot. Siehe https://bugs.launchpad.net/ubuntu/+source/shorewall/+bug/1511869

Abhilfe: Einbau eines Service Files in systemd, /etc/systemd/system/shorewall.service:
[Unit] Documentation=man:shorewall Description=Configure the IPv4 firewall at boot time DefaultDependencies=no After=local-fs.target systemd-sysctl.service Before=network-pre.target shutdown.target Wants=network-pre.target Conflicts=shutdown.target [Service] Type=oneshot RemainAfterExit=yes TimeoutSec=30 Restart=no IgnoreSIGPIPE=no KillMode=none ExecStart=/etc/init.d/shorewall start ExecStop=/etc/init.d/shorewall stop ExecReload=/sbin/shorewall $OPTIONS restart $RESTARTOPTIONS [Install] WantedBy=network-online.target

Danach systemctl enable shorewall.service

Grub update warning in Ubuntu 14.04
sudo update-grub Generating grub configuration file … Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

Abhilfe
/etc/default/grub.conf #GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT_STYLE=hidden

Info 'GRUB_TIMEOUT_STYLE'

If this option is unset or set to 'menu', then GRUB will display the menu and then wait for the timeout set by 'GRUB_TIMEOUT' to expire before booting the default entry. Pressing a key interrupts the timeout.

If this option is set to 'countdown' or 'hidden', then, before displaying the menu, GRUB will wait for the timeout set by 'GRUB_TIMEOUT' to expire. If <ESC> is pressed during that time, it will display the menu and wait for input. If a hotkey associated with a menu entry is pressed, it will boot the associated menu entry immediately. If the timeout expires before either of these happens, it will boot the default entry. In the 'countdown' case, it will show a one-line indication of the remaining time.
