I fail to use remus with xen-unstable (4.1)+ Linux-2.6.18.8:
[root@server1 img]# xm create rhel5.hvm
Using config file "./rhel5.hvm".
Error: Device 768 (tap) could not be connected. server1:9000|aio:/dev/vgxen/hvmsnap does not exist
Am I missing something? Any hints will be appreciated.
the config should like following:
disk = [ 'tap:remus:bkup:9000|aio:/dev/vmdisk/myguest,xvda1,w' ]
According to my understanding，remus doesn't need the support of DRBD, cause it can continuously send memory state to backup server as well as write operation and network
packages. So, what I do is to only ensure that /dev/vgxen/hvmsnap existing on both the primary and the backup and contain identical data.
My config file:
1 import os, re
2 arch = os.uname()[4]
3 if re.search('64', arch):
4 arch_libdir = 'lib64'
5 else:
6 arch_libdir = 'lib'
7 kernel = '/usr/lib/xen/boot/hvmloader'
8 builder = 'hvm'
9 memory = '512'
14 disk = [ 'tap:remus:server1:9000|aio:/dev/vgxen/hvmsnap,hda,w']
16 vif = ['type=ioemu, mac=00:1c:3e:17:22:13']
17 #boot = 'dc'
18 boot = 'c'
19 name = 'Rhel5-hvm1'
20 acpi = 1
21 apic = 1
22 device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
23 vnc=1
24 vncdisplay=2
25 sdl=0
26 opengl=1
27 vnclisten="0.0.0.0"
28 vncpasswd=''
29 serial='pty'
"hvm.hvm" 29L, 975C
Thanks for any help.
