kommt, so sind die Schlüssel für das Debian XEN Repository zu aktualisieren.

Die Aktualisierung des Keys ist durch
wget -q http://updates.vmd.citrix.com/XenServer/5.5.0/GPG-KEY -O- | apt-key add -
möglich.

Hierzu verwendet man den Befehl xe vm-import.
command name : vm-import
reqd params : filename
optional params : preserve, sr-uuid, force
description : Import a VM. If the option preserve=true is given then as many settings as possible are restored, including VIF MAC addresses. The default is to regenerate VIF MAC addresses. The VDIs will be imported into the Pool's default SR unless an override is provided. If the force option is given then any disk data checksum failures will be ignored.

Z.B.
[root@xen213 xvavg]# time xe vm-import filename=017-otrs.xva preserve=true

Jetzt sind noch die Netzwerkeinstellungen (virtueller Switch) zu überprüfen und die Maschine hat ihren neuen Wirt gefunden.

Daher ist es empfehlenswert, den Export in eine .xva-Datei über die Befehlszeile auf ein Netzlaufwerk, lokale Platte oder USB-Disk vorzunehmen.

Anzeige aller VMs, die exportiert werden könnten (status: halted)

xe vm-list params=all power-state=halted

Wichtig ist für uns der vm-name bzw. die uuid. Jetzt können wir den Export starten.


[root@xen211 ~]# time xe vm-export filename=/tmp/export/017-otrs.xva vm=09faa5ff-ceea-1234-e02e-97cae69878d5

-rwxr-xr-x 1 root root 4234127360 Jun 24 20:28 /tmp/export/017-otrs.xva

Sofern die Maschine nicht für den Export bereit ist, kommt eine entsprechende Meldung, z.B.
Another operation involving the object is currently in progress
class: VM

]]> http://tiri.li/wissen/openwrt/customizing-openwrt-on-asus-wl500gp/feed/ openWRT auf ASUS WL500gP http://tiri.li/wissen/openwrt/openwrt-auf-asus-WL-500gP-Premium-Router http://tiri.li/wissen/openwrt/openwrt-auf-asus-WL-500gP-Premium-Router#comments Sun, 15 Mar 2009 20:45:26 +0000 tirili http://tiri.li/?p=108 Heute habe ich einen Router von ASUS mit dem aktuellen openWRT 8.09 bestückt.

Die Vorgehensweise war folgendermaßen:

Flash-Skript

Um den Router bequem flashen zu können, kommt es auf Sekunden an. Daher habe ich ein Skript erstellt, welches das WRT-Image dann schnell via TFTP auf das System bringen kann.

#!/bin/sh
/sbin/arp -s 192.168.1.1 00:11:22:AA:BB:CC
/usr/bin/atftp --trace --verbose --local-file openwrt-brcm-2.4-squashfs.trx --remote-file openwrt-brcm-2.4-squashfs.trx --put 192.168.1.1

Los gehts

Vorbereitungen auf der Konsole (als root)

( ping 192.168.1.1 2>&1 | grep -v "Unreacheable" ) &
mii-tool -w &

Auf dem Router drücken wir die “EZ-Setup” Taste und schalten den Strom ein.
Durch das mii-Tool können wir sofort sehen, wenn das System nach Stromgabe einen Link hat.
Wenn der erste Ping antwortet, dann können wir mit dem Flashen beginnen, indem
wir die EZ-Setup Taste loslassen und unser flash.sh Skript starten.

Trace mode on.
Verbose mode on.

sent DATA <block: 2, size: 512>

...
sent DATA <block: 4233, size: 512>
received ACK <block: 4233>

Jetzt noch ca. 5 Minuten warten und den Router booten.

Was macht XENserver da ? Es erstellt ein Archiv mit allen Daten der VM.

Die exportierte Maschine können wir jetzt mittels scp auf einen anderen XENserver bringen und dort
importieren. Da wir eine identische Kopie wollen mit denselben MAC-Adressen, wird der Parameter “preserve” verwendet.

xe vm-import filename=/data/xtradius.xvm preserve=true

Nach ca. 20 Minuten ist die VM komplett verfügbar, taucht auch im XENcenter des neuen Hosts auf und
kann gestartet und genutzt werden. Allerdings hat die Maschine nun eine neue UUID, weshalb man beim Skripten besser auf den Namen gehen sollte.

xe vm-start name-label="xtradius .178.14"

Alternativ kann man import und start auch verknüpfen:

xe vm-start uuid=$(xe vm-import filename=/data/xtradius.xvm preserve=true)

Für uns interessant sind alle Zeilen, die die vdi-uuid enthalten, und dort auch nur die, die in der Datenbank vorhanden sind, also auch im LVM sichtbar sind.

xe vbd-list params=vdi-uuid vm-uuid=742ba99e-5f8b-b29d-e5a4-2f0e647838cb | awk '/[:alnum:]/ && !/not in database/{print $NF}'

Die zugehörigen LVs heißen dann

lvs | grep -E $(echo $(xe vbd-list params=vdi-uuid vm-uuid=742ba99e-5f8b-b29d-e5a4-2f0e647838cb | awk '/[:alnum:]/ && !/not in database/{printf "|%s",$NF}' | cut -c2-)) | awk '{print $1}'

Soweit so gut. Jetzt müssen wir die virtuellen Platten noch exportieren, am besten auf unseren lokalen Storage (wenn auch NFS oder eine Pipe ebenfalls möglich wäre). Hierzu sollten wir (generell) eine lokale Datenpartition nutzen.

lvcreate -n datalv -L 20G VG_XenStorage-fa726b3d-8ba1-dc56-e22a-2bec0b519663
mkfs.ext3 /dev/VG_XenStorage-fa726b3d-8ba1-dc56-e22a-2bec0b519663/datalv
tune2fs -c0 -i0 /dev/VG_XenStorage-fa726b3d-8ba1-dc56-e22a-2bec0b519663/datalv
mount /dev/VG_XenStorage-fa726b3d-8ba1-dc56-e22a-2bec0b519663/datalv /data

Damit wir allerdings auf die LVs der virtuellen Maschinen überhaupt zugreifen können, müssen wir
die VG erneut einlesen.

vgchange -a y

Jetzt kann der Export stattfinden.

dd if=/dev/VG_XenStorage-fa726b3d-8ba1-dc56-e22a-2bec0b519663/LV-854c68ca-ce5c-4e02-8101-3dce30e847dd of=/data/xtradius-4G.img bs=1M
4096+0 records in
4096+0 records out
4294967296 bytes (4.3 GB) copied, 219.663 seconds, 19.6 MB/s

Diesen bringen wir mittels scp auf den neuen Server (auf dem bereits eine datalv gemountet ist).
Im Gigabit Netzwerk klappt das für unser 4GB Image in wenigen Minuten (ca 20-30MB/sec).

Auf der anderen Maschine erzeugen wir uns wieder eine VM in der wir die Images in die entsprechenden lokalen LVs hineinbringen.

Soweit EDV zu Fuß. Viel gelernt, viel Skripting, aber es geht auch einfacher mittels xe vm-export ;-) !

Ich habe aktualisierte Pakete für httpd-2.2.10 und php-5.2.6 unter RHEL4.7 erstellt.

chown -R apache.apache websvn-2.1.0
mv websvn-2.1.0 websvn
chmod 777 websvn/cache

Konfiguration

Um WebSVN zum laufen zu bringen, muss eine Minimalkonfiguration in include/config.php angelegt werden.

<?php
 
$config->useGeshi();
$config->parentPath("/srv/subversion/repos");
$config->setTemplatePath("./templates/calm/");
 
?>

Jetzt kann der Zugriff über http://subversion-server/websvn/ erfolgen.
