Re: Cloudstack 里的VM，可以指定IP吗？
建好的vm不能随意改ip。 CS默认的ui上没有改ip的功能，但是通过api可以实现在建vm的时候制定ip地址。 刘宇超 Richard Liu 发件人： Nick 发送时间： 2013-11-18 11:54:59 收件人： users-cn@cloudstack.apache.org 抄送： 主题： Cloudstack 里的VM，可以指定IP吗？ Hello All 想请教一下，在Cloudstack 里的VM，可以修改IP吗？ 因建好后，DHCP会自动发一个IP给VM，不知这个是否可自行修改呢？？ Thanks Nick

数据库中有个表会记录ip的使用情况不同的ip有不同的表，公共ip，管理ip，存储网ip，guest ip都有。 删除vm后，ip会释放，留给以后用。 刘宇超 Richard Liu 发件人： toudsf 发送时间： 2013-11-18 16:57:48 收件人： users-cn 抄送： 主题： 回复: Re: Cloudstack 里的VM，可以指定IP吗？ DHCP的租期好像是20年，如果删除这个虚拟机。 其他虚拟机还会分配到这个IP地址吗？ 2013-11-18 toudsf 发件人：tanthalas tanthalas...@hotmail.com 发送时间：2013-11-18 16:54 主题：Re: Cloudstack 里的VM，可以指定IP吗？ 收件人：users-cnusers-cn@cloudstack.apache.org 抄送： 建好的vm不能随意改ip。 CS默认的ui上没有改ip的功能，但是通过api可以实现在建vm的时候制定ip地址。 刘宇超 Richard Liu 发件人： Nick 发送时间： 2013-11-18 11:54:59 收件人： users-cn@cloudstack.apache.org 抄送： 主题： Cloudstack 里的VM，可以指定IP吗？ Hello All 想请教一下，在Cloudstack 里的VM，可以修改IP吗？ 因建好后，DHCP会自动发一个IP给VM，不知这个是否可自行修改呢？？ Thanks Nick

目前看是权限的问题，不知道是否影响你系统运行，因为/opt这是个系统默认目录，不建议你用来挂载，建议你使用/mnt /media这类的目录。一般不会出现这样的错误。 刘宇超 Richard Liu 发件人： wanghaicheng2...@126.com 发送时间： 2013-11-19 10:05:38 收件人： users-cn 抄送： 主题： 回复: Re: 系统虚拟机安装报错 /opt目录是本地的目录，此处用于挂在nfs的共享目录 /export/secondary1 wanghaicheng2...@126.com 发件人： tanthalas 发送时间： 2013-11-19 09:59 收件人： users-cn 主题： Re: 系统虚拟机安装报错 /opt 这个目录是你的nfs共享目录，或者是挂载路径吗？ 刘宇超 Richard Liu 发件人： wanghaicheng2...@gmail.com 发送时间： 2013-11-18 19:33:58 收件人： users-cn 抄送： 主题： 系统虚拟机安装报错 XenServer6.0.2+CS3.0.5 安装系统虚拟机报错，但是有提示完成。什么情况？之前的安装怎么没有出现过呢 [root@master ~]# /usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt -m /opt -f /root/acton-systemvm-02062012.vhd.bz2 -h xenserver -F Uncompressing to /usr/lib64/cloud/agent/scripts/storage/secondary/bc979997-91de-4623-8a71-c580dc37e6e5.vhd.tmp (type bz2)...could take a long time Moving to /opt/template/tmpl/1/1///bc979997-91de-4623-8a71-c580dc37e6e5.vhd...could take a while mv: failed to preserve ownership for `//opt/template/tmpl/1/1///bc979997-91de-4623-8a71-c580dc37e6e5.vhd': Invalid argument Successfully installed system VM template /root/acton-systemvm-02062012.vhd.bz2 to /opt/template/tmpl/1/1/ wanghaicheng2...@gmail.com

System VMS show running in both UI and through virsh command line. However they are not reachable and cannot open their console.

Networking also seems a bit more complicated. Any tips would be wonderful! Right now we are using OpenStack but I getting very annoyed with it. Thanks, Sam Hi Sam, good to hear you want to take cloudstack for a tour :) If you want to encapsulate everything (cloudstack management and hypervisor used to spawn VMs) within a VM. There are different ways to do this: DevCloud: https://cwiki.apache.org/confluence/display/CLOUDSTACK/DevCloud It's pre-packaged and baring a few caveats, you will get CloudStack running quickly. However it's a Xen kernel. If you are a KVM guy: the easiest way to do this would be to use vmware workstation or fusion to take advantage of hardware virtu. You can then use KVM directly within the VM and setup CloudStack for testing. You can then follow this guide: http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/qig/index.html to setup everything on your own. Someone did it the other day in 20 minutes. -Sebastien
CS Storage best practices
Hi Folks, I'm beginning on cloudstack 4.2 and I would like to know the best practices about the storage. I would like to know what kind of storage do you recommend or prefer to use for the primary and secondary storage? Which important point should we be meticulous on for the primary (i.e performance) and the secondary storage (i.e high capacity). If you have some interesting link don't hesitate to share. Thanks in advance for your feedback. Pascal
Re: CS Storage best practices
Hello Pascal , Primary storage depend what you want or offer, if you have a money get fc hba get fc storage or use ssd storages for high performance If you need automation use supported storages like netapp , solid fire If you are open to open world use ceph could be very interesting with QEMU/KVM About secondary storage use and nfs storage linux or official ones Another options S3 interfaced storages You can use basho riak cs Myself we will use nfs server for secondary optimising s3 based storage could be problem (for now, no experiences i have) Regards Vahric On 18/11/13 17:23, Pascal KOUAME AKA p.kouame@gmail.com wrote: Hi Folks, I'm beginning on cloudstack 4.2 and I would like to know the best practices about the storage.

Re: Guest VMs not able to acquire DHCP IP from Virtual Router unless Guest and VR are on the same KVM host
Hi David,
Thanks for the reply.
I just did some more troubleshooting and I can definitely see using
dhcpdump on the VR that it only receives a DHCPREQUEST when the Guest VM is
on the same KVM Host. If I migrate the guest to any other KVM Host that
request never even makes it to the VR. I monitored the physical KVM host
running the VR, but it never registered the DHCPREQUEST regardless of where
the guest VM was running.
I even turned off the firewall on both KVM Hosts and still no DHCPREQUEST.
There actually is another physical DHCP server on the same network. *10.97.38.1
Router DHCP*
However we (corporate IT Admin) have blocked off a range of IPs
{10.97.38.[110 -170]} from the 10.97.38.1 Router DHCP and filtered out
any DHCPREQUESTS made by a '06' MAC address per these instructions (written
by you I believe):
http://open.citrix.com/blog/42-tip-of-the-month-external-dhcp-server-and-cloudstack-on-the-same-network.html
So that tells me that we probably did something wrong on the router and
it's got to be the 10.97.38.1 Router/Switch/DHCP server that's stopping
those requests from ever reaching the built in VR, but I have no visibility
into that unfortunately so I cannot continue to test. I need to be able to
give very precise instructions to my IT Admin on what to check.
Thoughts?

If I remove the NFS storage I've got now and for some reason either can't get S3 to work or decide I want to put the old NFS storage back in, is that possible? How do I migrate what is in the secondary storage to S3?

At this moment, you can only add a region-wide S3 when there is no NFS secondary storage existing. When you add S3 into system, system vm templates will be automatically uploaded to S3.

I just don't know hot can I add it now. I've got the existing secondary storage over nfs and if i delete it, would I not loose the data? Most likely the data will not be removed from the storage server itself, but all references will be removed i suspect. So, what is the best way to proceed I wonder?
