Sequence table recovery possible?
Yo cloudstack users and devs! A corrupt HDD caused my mysql cloud.sequence table to become corrupted (misconfig didn't put mysql data dir on zfs). I have multiple cloudstack installations though and am able to look at a valid sequence table example: mysql> select * from sequence; +-+---+ | name| value | +-+---+ | checkpoint_seq | 1 | | networks_seq| 218 | | physical_networks_seq | 202 | | private_mac_address_seq | 1 | | public_mac_address_seq | 1 | | storage_pool_seq| 200 | | vm_instance_seq | 202 | | vm_template_seq | 215 | | volume_seq | 1 | +-+---+ 9 rows in set (0.00 sec) For my now corrupted cloudstack database, is there any way to glean the appropriate values that I can use to repopulate the table? I'm hesitant just copy the table from my valid instance for obvious reasons. Any idea how I can recover the appropriate values for physical_networks_seq, physical_networks_seq, storage_pool_seq, vm_instance_seq, vm_template_seq? Thanks in advance, Z

local storage ?
Hi there, I have a KVM hypervisor with 8 locally attached drives. I would ideally like to add the 8 drives to a VM and allow them it to leverage all of the spindles simultaneously. Reading through the documentation, I don't see any obvious way to do this. The reason I seek a configuration of this type is because that is what is recommended for a host running the Kafka queueing service. Any assistance on this matter would be greatly appreciated. Thank you! Sincerely, Z
Re: local storage ?
Damn, was hoping for JBOD. Additionally, I don't have a raid controller. Thanks anyhow.

Zone DNS, Virtual Routers, and DHCP
Hi dudes, I'm trying to host DNS off of one of the VMs that I have here in the KVM cluster. Any way to set a static IP for a server (or more preferably a static DHCP lease)? I tried changing the zone DNS IP to that of my DNS VM but I have to restart the virtual routers which then causes my DNS VM to get a new IP. Is the only real solution here to run my DNS on bare metal? Thanks, Z

Re: Cloudstack 4.2.1, KVM Advanced networking headaches
Tanner, I myself am very new to cloudstack so take what I say with a few grains of salt. I am using KVM with bonded interfaces as well though mine are in active/active mode (switch supports it). Additionally, I used Centos rather than Ubuntu. I have never been able to get CloudStack KVM to work when I tried to do the management on the same bond as the guest/public networks. For my configuration, I set up 1 dedicated interface for management (on the switch this was configured as an access port) and then configured it to bridge via cloudbr0. Then, I set up my bond0 interface to bridge to cloudbr1. On advanced zone configuration, I set my management network KVM label to be cloudbr0 and then both public and guest kvm labels to be cloudbr1 (note that on the switch the aggregated port connecting to the bond0 physical port was configured as an 802.1q trunk). After that, my biggest difficulties were to get the VLANs for the guest up and running, as well as ensuring that the public network had access to a DNS server, and internet routing so that the SSVM could download the default template as well as connect to the secondary storage. If you have a 3rd NIC card in those machines, my advice would be to that for management and leave the guest/public networks to the bonded interface. If you don't have a 3rd NIC, forget about the bonding and just use one NIC for guest/public and one for management. I'm sure that there is a way to get around this but after an excruciating number of attempts, this has been the only way that I've found to make it work. I'm sure that the dudes on this list might have some better advice though because as I said, I'm rather new to CloudStack. Good Luck, Z On Tue, Feb 4, 2014 at 9:50 AM, Tanner Danzey arkan...@gmail.com wrote: Hello all. My name is Tanner Danzey. Just a little introduction since this will be my first post to this list. I am from Fargo, North Dakota and I have had fairly significant Linux Linux server experience for about four years. My coworker and I are working on rolling a Cloudstack cloud using Ubuntu 13.10, Ceph, Rados Gateway (S3) and KVM and commodity hardware. We currently have our Ceph and Rados setup under lock and key as far as our testing can tell. Installing the management server is a breeze, so that's not an issue either. Our issue seems to be of a networking nature. Our desire to use advanced networking has been made complicated by our other desires. Originally we planned to use many LACP trunk configurations to achieve highest bandwidth and redundancy possible, but our discovery that the switch we are using (two Catalyst 2960 48 port switches in stacked configuration) only allows for six port channels complicated that plan. Now we are still using bonded adaptors but in active-backup mode so that we do not need switch side configuration tricks or port channels. I have attached an example of our KVM hypervisor configuration. We have interface bond0 in active-backup mode bridged with em1 and em2. Both of those ports are connected to switch trunk ports. Here's where things get silly. Our KVM nodes are able to be pinged and managed on the management IP assigned and when we create a zone and assign the bridges their respective traffic. However, they are not connected to the public network. Some variations of this configuration even result in no connectivity other than link local. Essentially, we are trying to find the best way to approach this situation. We are open to using Open VSwitch. Our VLANs will be 50 as public, 100 as management / storage, and 200-300 as guest VLANs unless there is a more pragmatic arrangement. Our plan after this deployment is to help brush up documentation where possible regarding some of these edge-case scenarios and potentially do a thorough writeup. Any and all help is appreciated, and if you require compensation for the help I'm sure something can be arranged. Thanks in advance, sorry for the overly long message :)
DNS question
Is it possible to name different DNS servers per network or per account? Example 1: I would like to provision a network for a customer that uses a DNS server they control. Example 2: I would like to provision a network and then a DNS server just for that network and all ensuing guests provisioned on that network should be assigned the locally provisioned DNS server. Thanks, Zack
Re: DNS question
Also curious if it's possible via CloudStack (without hacking up the virtual routers) to create a permanent static DHCP lease for a VM? If I'm going to start creating DNS entries for hosts on the network, I want to ensure that they won't change.

Server address passed to cloudstack agent
Hi there, I have multiple IP addresses assigned to the CS Management server on different VLANs. When I go add the host to the Infrastructure it tries to connect back the wrong IP address and is thusly blocked by our inter-vlan access policy. What's recommended mechanism for specifying the server IP address? cloudstack-setup-agent -m *10.1.1.2* -z 1 -p 1 -c 1 -g 03408e21-366b-3d94-8fe0-23aa00416bfd -a --pubNic=cloudbr1 --prvNic=cloudbr1 --guestNic=cloudbr1 Here, the setup-agent script is passed 10.1.1.2 when it really should be passed 10.1.2.2. Any assistance on this matter would be appreciated. Thanks, Z
Re: Server address passed to cloudstack agent
Thanks guys. In the end I just set the Global Settings host variable and that worked great rather than messing around with the host files as there are other services currently running on the box that depend on hostname --fqdn coming back with the hostname that resolves to 10.1.1.2. Responses much appreciated. Z On Sun, Feb 2, 2014 at 5:54 PM, Kirk Kosinski kirkkosin...@gmail.comwrote: Hi, the IP host connect to can be configured with the host parameter in Global Settings. The initial setup probably detected the 10.1.1.2 IP and configured the host parameter with it, but you should change it to the desired IP.

I found the solution after digging into the code. Essentially you need to configure your host to pass the hostname --fqdn test before the SnmpAppenderTest class will pass the junit test. I simply added my hostname to /etc/hosts and was able to build successfully. Just wanted to share so if anyone else caring to build from source ran into this issue, that they would know what to do. FYI, this was on Centos 6.4 64-bit with Cloudstack 4.2. Sincerely, Z
