[Openstack] Openstack installation on multiple host belongs to different network
Hi, Stacker We would like to install openstack on our several spare computers, when all of them are in the same network, it works well. But when we try to install openstack on hosts in different network, the VM in compute node, which is in different network from controller node, can't be accessed. To be specific, assume we have two hosts, controller(10.0.0.1) and compute-node(10.0.10.1), has different network. The VM in 10.0.10.1 can not be accessed. In 10.0.10.1, we only install nova-compute, nova-network, and use mysql, rabbitmq, etc in controller(10.0.0.1) My question is: Is there some installation guide for this case, or some of you have experiences on this?

Re: [Openstack] Can't Migrate a VM?
Your ssh key may be not config properly. Checkout following steps. 1. You get a key pair( pub key and private key). You can using the root's key which locate `/root/.ssh/id_rsa` and `/root/.ssh/id_ras.pub` or generate a new one 2. Enable the nova user login-able ``` usermod -s /bin/bash nova ``` Now you can switch nova account by using following command, and steps bellow is operated under this account. ``` su nova ``` 3. Create the folder needed by ssh and put the private key got in step 1 ``` mkdir -p /var/lib/nova/.ssh cp private_key /var/lib/nova/.ssh/id_rsa cat pub_key /var/lib/nova/.ssh/authorized_keys echo 'StrictHostKeyChecking no' /var/lib/nova/.ssh/config ``` 4. Do the steps 2-3 on each nodes. IMPORTANT: All the nodes share the same key pair and you shouldn't generate new one in second node. 5. Check the key is working properly. ``` su nova ssh nova@node-another // you will login the node-another without password ``` On Wed, May 29, 2013 at 8:59 PM, Nehal J.

Re: [Openstack] more info on this raise exception.NoValidHost
Yes, nova-scheduler has lots of filters to check if nova-compute node fit the requirement of the instance you wanna launch. Like availability-zone filter, RAM filter, cpu core filter, etc. If all the compute node failed to pass those filters, it raise this exception.

Re: [Openstack] keepalive can not check the haproxy is down.
I am using the default version of the ubuntu 12.04 ( keepalived
1:1.2.2-3ubuntu1).
Maybe this issue is the root cause. I will try the latest keepalived.

I would first try removing the check script and validating that failure
works without the check script. If that works you might need to update
keepalived.

Here’s a brief introduction I did a while back on using haproxy with
keepalived as a load balancer (FWIW):

Thanks Eric,
I have solve it after breaking down the group.

1. the different netmask is typo. And it doesn't break the failover.
2. Why the group is unnecessary? When there are the two instances using
the same check script , like this case, what's mean after grouping them?**

Hi Guys,
I am trying to use keepalive and haproxy to work together to improve the
HA of the openstack. But I meet following
unexpected issue.
I expect that when the haproxy process is crashed on the MASTER
node(checked by chk_haproxy), the second node
will take over the VIP. But when I stop the haproxy process, nothing is
happened.
However, when stop the keepalived service, the VIP is set up on the node2
as expected.
So I think the root cause should be the chk_haproxy block. But I have no
idea why it doesn't work. Does any body have
ideas?

[Openstack] What's the package flow in vlan mode when ping the floating ip between vms.

Re: [Openstack] What's the package flow in vlan mode when ping the floating ip between vms.
Hi JuanFra, I read this article. But It doesn't explain what I concern. What I want to know is that what's the packet flow when ping the floating ip between the VMs which located in the same physical machine?

[Openstack] How to make HA between VMs in the openstack
Hi all, I am using Folsom, and I want to set up a HA between VMs. For example, I have two DB VMs. One is the primary and other is a slave. I want to use Keepalive or pacemake to switch between them when one is failed. But how to implement this? Because in general, we need a dynamic IP to associate to the VMs and change the relationship when necessary. But which IP should be used ? Floating ip or Fixed IP? and how. -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

Re: [Openstack] How to make HA between VMs in the openstack
Hi Ritesh How could I switch the virtual ip from one VM to another? As I know, the libvirt nw-filter will block this? right? Or not use nw-filter?

Another question, what's you mean about FIP? floating ip? But how can I switch the floating IPs and implement with keepalive/pacemaker?

But there is a caveat with RHEL6 which is Linux 2.6 (contrary to Ubuntu 12.04 which is Linux 3.0). If you look at man resize2fs : Please don't do this, or rely on this. Having the hypervisor do this for your guest is simply wrong. Hypervisors should know little to nothing about the internals of the instances they're launching. Just to point out the alternative for when the VM doesn't have the smarts to resize itself, is to use something like virt-resize: https://blueprints.launchpad.net/nova/+spec/resize-no-raw Using libguestfs is worlds better than having the host directly do it. But really whats happening here is *still* something with very little information mucking with (and possibly breaking) the inside of a disk image. The more we consider that a bucket of bytes the better. If you are using libguestfs, chances are you're using it from your distro, and patching it to deal with a new filesystem (or otherwise get the update to your hostOS) is still problematic. Just let/expect the guest do it, and we'll avoid a whole silly game of cat and mouse that doesn't even have to be played. When was the last time you updated your bios on your laptop so you could use a new linux filesystem? That sounds silly, doesn't it. Having openstack reach inside the contents of the disk is just as silly. One of the major benefits of having cloud-init direct the partition resize *and* subsequent filesystem resize is that the user can (in user-data) disable this! (currently the initramfs doesn't take any instruction from user-data, so disabling it isn't really a possibility). perhaps they didn't want that extra instance-store space to be part of the root filesystem. If you put that function inside the hypervisor, you either can't do it, of you have to expose some silly api-launch parameter of do_not_modify_disk. It complicates the API and complicates the host. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

Hi all, I am curiosity about some parameters when create network. by the way, I am using list below. * folsom * nova-network * kvm + libvirt 1. what's means by --fixed_cidr. I found nothing different when using this parameter. 2. It seems the openstack not working very well when create two networks. when launch new instance. The instance get the two ip correctly both in openstack ( including db, dnsmasq). But in the libvirt, the nwfilter only accept one of the two IPs. The result is that only one ip is works.

Migrate is a 2-steps process: once the instance reaches the VERIFY_RESIZE stage, you need to run nova resize-confirm if you're happy with the new instance (this will delete the old one), or nova resize-revert if you want to go back to the old instance (this will delete the new one). Migrate and resize use the same mechanism, hence the naming of these 2 commands. There probably should be something to indicate this in the 'nova help migrate' command, since this is something many people seem to get caught in when first running migrate - myself included.

[Openstack] How to do when the compute-node is failed.
Hi all, I am confused about how to do when the compute node is failed. For example, if the compute node reboot. I found the VMs on it didn't startup automatically. I must reboot the VMs manually. Is there any way to keep the HA? In a bad situation, what should do if the node is crashed?

Re: [Openstack] It is stuck when attach the volume to the vm.
Hi Alberto,
I have fix this issue already. The root cause is that the controller(where
the cinder service located) block the 8776 port and the node can not access
the cinder service. After enable the port on the IPtables, it works.
thanks you.

Re: [Openstack] A confuse about the FlatDHCP network
thank you very much, Vishvananda. But I am still confused about the 192.168.0.0/24 and the 10.0.0.0/8 ip. What means by The addresses will be moved on to the bridge. It means the 192.168.0.0/8 will be disappear? In my opinion, the bridged NIC (eth1) should be worked under promiscuous mode and its IP should be 0.0.0.0. So the eth1 should not own any IP. But if the 192 address doesn't exist, how the compute-note communicate with each other? Through the eth0? I have no idea.

Strange. I didn't know that. Hi! The following description is libvirt specific. Bearing in mind that this code is a moving target and has been re-written at least three times in the last year [1], it works a bit like this... - you request an instance using a given image - that image is fetched to _base from glance (if its not already there) - that image is format converted if required, and then resized to the requested size - the instance disk image is a copy-on-write layer on top of that resized image in _base and is stored in the instance's directory - the instance is booted using the COW layer If another instance with the same image / disk size starts, it can short circuit the process and use the already existing image, which is cool. When an instance is terminated, the instance directory is removed, but files in _base remain. If you have image cache management turned on, then the files in _base are periodically cleaned up. The files in _base are also checksummed to try and detect file corruption, although that hasn't been the most loved feature ever implemented. Hope this helps, Michael 1: Several times I have gone to write a blog post about how this works, and then realized the code has changed again. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

First of all, I think this feature is reasonable. In my scenario, I have two projects. One is a test env and another is production env. I use different projects to isolate the two env. All should I do is to prepare in the test env. When all is ok, I can push it to the production env. @Tim, you are right. The permissions is a big potentail issue.

Re: [Openstack] LVM over LVM is acceptable?
Got it. Could Cinder can check the created volume? I can not find any command like cinder update. I try to extends the volume by lvextend, but data in the cinder db doesn't update. So when I delete the changed volume, it raise error.

Re: [Openstack] LVM over LVM is acceptable?
I think the extend the size the volume is reasonable and easy implementable. But the shrink of the LV is very dangerous. So add the feature of extends the Volume size for the Cinder is OK. Could you guys agree with me?

[Openstack] LVM over LVM is acceptable?
Hi all, I have a scenario for using cinder with tgtd over the lvm. I creat a lvm named vol-0 and attach it to the machine com-0. After a period of time, the vol-0 is full and I want to extend it. At now, I have two solutions. 1. Because the vol-0 is manage by the LVM on the hoster. So I can extend the size of it by using lvextend. But I meet that the vm(com-0) can not be aware this. Should I make some extrac operations like reseize2fs? I have no ideas. 2. In the vm (com-0), I can treat the vol-0 as a normal block device and create lvm on it. When need more space, the hoster can plug a new lvm device(vol-1) on it. In the vm, I can add it to the lvm. But I found another problem. Because the vol-* is not real block device, when I create lvm on it, the hoster is aware of it. The result is that on the hoster, another PV is created base on a lvm partition like bellow. I want to know, it is acceptable? --- Physical volume --- PV Name /dev/cinder-volumes/volume-ddac25fc-4cc2-4167-be12-4cef2438de0b VG Name data PV Size 30.00 GiB / not usable 4.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 7679 Free PE 2559 Allocated PE 5120 PV UUID zChRw9-nVru-rF5o-YYUx-hcIa-Zen4-Ff5IOf Besides these two solution ( with issue ;) ), could you give me some better suggestion? -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] LVM over LVM is acceptable?
Understood. Another question. If the vm treat the vol-0 as a normal block device, is it necessary to partition? If not, the fdisk will show Disk /dev/vdb doesn't contain a valid partition table. If yes, how can I extend the volume on the vm? It seems that treat the volume as a normal block device is not a good idea.

After a period of time, the vol-0 is full and I want to extend it. At now, I have two solutions. Nested LVM gets tricky so I want to be sure I am clear on your setup: * Your host has a logical volume (LV) 'vol-0' that is attached to a VM named 'com-0'. * com-0 uses the attached logical volume (vol-0 on the host) as a physical volume (PV) for its own LVM configuration. Because the vol-0 is manage by the LVM on the hoster. So I can extend the size of it by using lvextend. But I meet that the vm(com-0) can not be aware this. Should I make some extrac operations like reseize2fs? I have no ideas. If vol-0 is used directly as a block device with a filesystem on it (older Xen installs often did this) then a resize2fs is sufficient to recognize the additional space. It appears this is _not_ your configuration, correct? If vol-0 is used as a PV in com-0 then you can run pvresize inside com-0 and have com-0's LVM recognize the additional space. In the vm (com-0), I can treat the vol-0 as a normal block device and create lvm on it. When need more space, the hoster can plug a new lvm device(vol-1) on it. In the vm, I can add it to the lvm. But I found another Correct, this is another way to increase the space available to cpm-0's volume groups. problem. Because the vol-* is not real block device, when I create lvm on it, the hoster is aware of it. The result is that on the hoster, another PV is created base on a lvm partition like bellow. I want to know, it is acceptable? To fix this you need to adjust the filter on your host's /etc/lvm/lvm.conf. You can either reject any physical volumes found for VMs: filter = [r|/dev/cinder-volumes/.*, a/.*/] # reject cinder devices, alow everything else or you can only look at particular divice files for physical devices: filter = [a/dev/sd.*] # look only at SCSI disks for physical devices That last one will likely need adjusting for your local block device names. dt -- Dean Troyer dtro...@gmail.com -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
