Openstack computer instances無法啟動

[Van]

各位大哥們好：
小弟不才，我無法成功的啟動instances
首先我先說明一下我的安裝背景
1.我是根據官方網站上的OpenStack Compute Administration Manual Cactus(Jun 8,
2011) 這份文件
2.安裝過程式根據該文件的3.4.2這部分下去安裝 (Scripted install) computer & node
3.安裝完成後我有試著自己做一個image，這部分也是OK的
4.網路配置部分computer & node都在同一個網段 10.32.29.X
希望啟起來的instances則是在10.32.74.X，這兩個的Gateware都是10.32.0.1

下面是我執行 euca-run-instances 後的nova-compute.log

看log說我BIOS的VT沒啟，但是我在BIOS中的設定的確是打開了
然後查了一下
root@sqad-Cloud-9:~# lsmod | grep kvm
kvm_intel 56851 0
kvm 367707 1 kvm_intel
看來KVM也是有開起來的

真的不太明白到底為什麼起不起來~~
我只是想開起來看看而已阿~~~
希望各位高手們可以給我一點指示吧
謝謝

There are probably a couple of issues here. One is that you will need
to use glance so that that the other node can grab images. You also
may have issues with kvm module and permissions:

sudo modprobe kvm
sudo chgroup kvm /dev/kvm
sudo chmod g+w /dev/kvm

Dear Hugo:
感謝你的回答
果然是br100沒有啟動...

但我目前只有一張網卡，啟用bridge也還是只有一張網卡
這樣我連的到我的instances嗎？

我試著在一台computer上起一個instances
computer的IP為10.32.29.78
instances為192.168.1.2
root@sqad-Cloud-8:~# euca-describe-instances
RESERVATION r-6rhqfyu8 mydlink default
INSTANCE i-00000007 ami-6d8a520d 192.168.1.2
192.168.1.2 running None (mydlink, sqad-Cloud-8) 0
m1.small 2011-07-19T03:16:30Z nova
root@sqad-Cloud-8:~# ping 192.168.1.2

ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted

這個是我測試的結果...

然後我也有試過在同樣網段的情況
root@sqad-Cloud-10:~# euca-describe-instances
RESERVATION r-u0hpc1l0 mydlink default
INSTANCE i-00000014 ami-2f1e6f20 10.32.74.2

PING 10.32.74.2 (10.32.74.2) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted

兩個的結果都一樣
我也沒特別設定防火牆...

1. Check console.log
2. ping 不到 我猜是dnsmasq沒辦法正常發ip
查一下dnsmasq 的daemon 的參數是否正確

hope it help

等一下!!!!
你有把security group 的 22 跟 icmp 打開嗎?

你的instance 有跑起來了，只是網路問題，請將console log 貼在pastebin 上，小弟幫你看一下，理論上ping 不到，八九不離十是dnsmasq daemon 的問題。

所以請將 

1. console.log 

2. ps aux | grep dnsmasq 

提供在pastebin 上 

Thanks

有空都OK

也算一種累積經驗的方式，我不可能遇過所有問題囉，所以這樣有好處沒壞處　我想

有三種原因，可以先讓我看一下你的dnsmasq 否？

我沒記錯的話　你現在是一台前端　一台運算結點？

這個image 是　tty image

Right?

Dear Hugo
太感謝你了...
我這邊都會遇到奇奇怪怪的問題...
我看了你和啤酒的blog好像都沒有在安裝的時候遇到這些問題...
一度安裝到很沮喪 -.-
想說按照這些文件怎麼跑出來還是有問題

目前的確是如您所說的
control node, computer node各一台
目前我的instances都是run在control node上
我跑在computer上的run不起來...
這個問題我想晚一點在解決

image是tty image也有官網提供的ubuntu1010-UEC-localuser-image.tar.gz
兩個都試過
都ping不到也ssh不到
想利用console也沒辦法
root@sqad-Cloud-10:~# virsh console 2
Connected to domain instance-0000001c
Escape character is ^]
error: internal error character device (null) is not using a PTY
dnsmasq kill掉就沒開了...

拜六在幫你看，兩天你可以好好休息or 裝看看Swift 

Swift 拿四五個VM來測試應該就可以了

謝謝...
我也很想繼續玩Swift...
但我現在被抓去玩其他東西了

虛擬系統必須設定 ttyS0 裝置

http://linuxkvm.blogspot.com/2011/05/linux-kvm_15.html 之前問過Linux KVM
研究室 的blog

可是我後來沒有嘗試，因為這個東西只是出自於好奇，再cloud 的IaaS 中 末端使用者是不能進入到 Cloud Platform 的
servers 上才對。

我指的console output 為

#euca-get-console-output i-0000xxxx
#/var/lib/nova/instances/instance-00000xxxxx/console.log

ok , 請用 vncviewer 分別連線 10.32.29.80:5900 , 及 10.32.29.80:5901 , 如果沒猜錯你的
10.32.74.2 就在 10.32.29.80:5901 , 進去後看一下 instance (vm) 的網路設定值 .

我連進去了，果然是裡面的設定有問題
GW是10.32.74.1，但我的GW應該要是10.32.0.1
所以連不到，我現在改了之後....可以ping
但是ssh連線不到
root@sqad-Cloud-10:~# ssh 10.32.74.6
Read from socket failed: Connection reset by peer

我在VM裡面下
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

在control node下

root@sqad-Cloud-10:~# euca-describe-groups
GROUP mydlink default default
PERMISSION mydlink default ALLOWS icmp -1 -1
FROM CIDR 0.0.0.0/0
PERMISSION mydlink default ALLOWS tcp 22 22

[Van]

看起來是沒有安裝ssh....
apt-get install openssh-server
就好了!!!!
太感謝了，總算把instences啟起來了

[Van]

所以目前起來是因為Default gateware的關係
下nova-manage network list
root@sqad-Cloud-10:~# nova-manage network list
network netmask start address DNS
10.32.74.0/25 255.255.255.128 10.32.74.2 8.8.4.4
發現這邊可能是造成default GW是10.32.74.1的關係
我現在去nova.conf裡面修改了
--fixed_range=10.32.74.0/24把這個改成
--fixed_range=10.32.74.0/16
然後restart所有的nova server
再下
nova-manage network delete 10.32.74.0/25
nova-manage network create 10.32.74.0/16
卻出現這個錯誤
Command failed, please check log for more info
請問有沒有辦法讓default GW改變成10.32.0.1？

[dck]

你目前nova 的版本 ?

[Van]

我用的nova為cactus

我目前是希望我啟的instances能啟在10.32.74.X
但是我的GW會是在10.32.0.1，DNS也會在10.32.0.1
但我不管怎麼弄預設的instances是會啟在10.32.74.X沒錯
但GW和DNS都不會是我想要的10.32.0.1
GW都會是10.32.74.1，DNS則為8.8.4.4
這樣的話不管我怎樣啟instances都必須進去VM裡面改設定
沒辦法直接使用bashboard啟用後就可以直接連進去...
這點是我比較苦惱的

[dick]

嗨 Van,

1.請試著下 nova-manage version list

2.你的網路上有dhcp server在運作嗎 ?

[Van]

我的DHCP server是10.32.0.1
這也是我的GW，DNS，都在同一台上

而我VM的確是拿到我限制的IP
10.32.74.X
但是VM裡面的GW卻不會是10.32.0.1
而是10.32.74.1...

可否 post 上來 dhcp.conf 及 dhcp server 的 ifconfig

[Hugo]

GW 沒問題，在diablo release 之前，instances 的gateway 都是在nova-network 這個host 上，代
表所有instance 的traffic 都走該台機器出去，這表示nova-network 是一台linux router.....
為什麼要這樣設計呢?
Reasons....
Cloud 有幾個重點Multi-tenant / platform 處理你所做這些手動的部分。 But how.... 在ubuntu 透
過Cloud-init 來處理，包含取得該instance 的metadata(內容可以google 一下)
由於Cloud-init 內會使用一個特殊IP(169.254.169.254)讓instance去擷取api server 上的資料來做
instance 初始化，包含instance hostname/routing table / SSH public key / user-
data etc....
那目前如何讓instance 透過制定好的IP去取得資料，這時候nova-network 會將169.254.169.254 的
request PREROUTING 到 nova-api_entry_point.
可是為了讓instance 169.254.169.254的請求正確，必須要透過nova-network 當成GW 。

剛剛提到的是需要initial 的instance.... 如果是自己包的image 不含cloud-init ...yes 你可以讓
instance gateway 走你要的IP，因為instance 並沒有cloud-init的需求，只要dhcp 設定改一下即可。
openstack 使用dnsmasq 負責dhcp 的工作。

那又如果你想要instance 有cloud-init 又不要走nova-network 出去，的確有方法。在外部gateway 上
prerouting , 一樣可以達到需求，好處很多，包含HA跟LB，可是會犧牲掉floating_ip的功能。因Floating_ip 是由
nova-network 的NAT 處理。(非標準做法，可是在private cloud上非常好用)

在diablo中，將會有幾個可行的選擇，敬請期待。fail_over/Multi-nics/HW gateway/multi nova-
networks

如果不依靠cloud-init 的方法，那有幾個條件
1. 包image 時，設好dhcp
2. 在fire up instance 時，把user-data 寫進去，讓instance 安裝ssh / 植入ssh key

如果cloud platform 不能處理這些部分，基本上，那就跟一般的虛擬化平台沒什麼不同了，甚至更不實用。
Cloud 我想最好

Re-use image , easy scale out , multi-tenant , automatic , large
scalability , un-limit resources ,

I'm drunk now.....

Dear Hugo:

我在control上多加了一張虛擬網卡，讓他跟br100串在一起
果然能實現我那天說我想要達成的目的

只是現在很怪，我在node上開instances卻開不起來
log說ClientConnectionError: Unable to connect to server. Got error:
[Errno 111] ECONNREFUSED

http://pastebin.ubuntu.com/651643/
但我這台node可以連到主機，也可以連到169.254.169.254
我不曉得他到底哪裡連不到？

[dick]

確實怪怪的,你目前的版本跟上一次的有差嗎?

[Kuo Hugo]

Hello , Van

1. telnet 連Glance ，從新增的compute node 上

2. 先將額外的node 拔掉，嘗試在all-in-one 上起看看結果

我有幾個疑問的地方

依照那天你想要的結果，那10.32.74.1 怎麼會還在聽DHCP 要求? 應該是用10.32.29.80 來聽

前端的NIC 是否都有起來??

依據那天你想要的結果

brctl show 

結果應該是

br100  綁 eth0 , eth0:1

eth0當成mgm network , eth0:1 當成instance network

If so, 這會有很大的問題。

在DB內　只能定義一張NIC 來做為Flat_network 的介面，也就是說，CC與NC 上的Flat_interface 是要相同eth0:1

不如先來張拓樸圖比較清楚一些

如果從NC telnet 連不到glance 那也許得先解決這件事情

Cheers

Hugo Kuo
