kvm host gets wrong IP address in host= at agent.properties
Hi all: I must be doing something wrong. I am installing 4.15 from the apt repositories on ubuntu 16.04 deb http://download.cloudstack.org/ubuntu xenial 4.15 Everything goes grandly, except that when cloudstack-agent starts up, it puts a seemingly random IP address (from the correct subnet) in host= at agent.properties. It should be host=172.16.10.2 but it picks up host=172.16.10.246@static Evidently, it passes this *.246 value on to the ssvm -- which makes it very mad. I've redone my management server and first kvm host a second time, and it got *.234 instead of *.246. I am doing these on a test network that is NATed off from the main network. That NAT network did have its own DHCP active. I've switched that off -- and will do another try (tomorrow). But does this sound like I've got a configuration missing -- or am I picking up a bum copy of the cloudstack-agent from the repo? or... ideas? thanks. --jay
Re: Unable to read/process CSR: Command failed due to Exception: java.lang.Exception
Christian, did you solve this (i just encountered your mail and see it is
yet unanswered)
the problem is with the certificate generation, it seems to try and
generate from an empty string (the csr/certificate signing request)
Not being able to sign in to the SVM is a problem but on vmware you would
use a specific command as described in [1]. Did you try `ssh -i
/opt/xensource/bin/id_rsa --p 3922 root@privateIP
OfTheHost`?

Jay, is this after you added the host to cloudstack or before?

Re: kvm host gets wrong IP address in host= at agent.properties
Hi Jay, Please note that `host` is the IP of the cloudstack management server, not the IP of the kvm host. If it is wrong, you can change agent.properties manually and restart cloudstack-agent. Please also check `host` in the cloustack global settings. -Wei On Tue, 28 Sept 2021 at 09:02, jay hs wrote: > Hi all: > I must be doing something wrong. > I am installing 4.15 from the apt repositories on ubuntu 16.04 > deb http://download.cloudstack.org/ubuntu xenial 4.15 > > Everything goes grandly, except that when cloudstack-agent starts up, it > puts a seemingly random IP address (from the correct subnet) in host= at > agent.properties. > > It should be > host=172.16.10.2 > but it picks up > host=172.16.10.246@static > > Evidently, it passes this *.246 value on to the ssvm -- which makes it > very mad. > > I've redone my management server and first kvm host a second time, and it > got *.234 instead of *.246. > > I am doing these on a test network that is NATed off from the main > network.

Re: kvm host gets wrong IP address in host= at agent.properties
Hi Jay, i would suggest the following approach: - set IPs manually for the all hosts you wont't to use OR use a different dhcp server (not the Cloudstack Managementserver) and work with static leases for the hosts - only the system vm's (instances of systemvm's, console proxys and later on virtural routers) using dhcp - while creating the zone, you then double check that you didn't use the whole managametn ip range in dhcp. You can specify parts of your management network for ip leaese - not the whole network. For example when using the wizzard and enter the informations for your "Pod Network" Name: Pod 1 Reserved System Gateway: Address of your Gateway Reserved System Netmask: Subnetmask of the whole Pod-Network Start / End IP Reserved System IP: IP Range used for leases to the system vms's - not the whole pod / management network Am Di., 28.

RE: Unable to read/process CSR: Command failed due to Exception: java.lang.Exception
Hi,
We already tested in all the ways is possible, this problem is related to
these specific servers, 100%.
The last test we did, was to add the ESXI server to the zone we already have
and works, we disabled all hosts from that zone and destroyed the SSVM to force
a redeploy on this ESXI, of course, we have ended with the same error.
I want to mention that we have the exact same ESXI version and hardware, for
me looks like there is a BIOS/HW/DISK issue.
FYI:
"I did this in 3 different new Setup (new Management install, NFS, etc), no
matter if I add as first zone or second zone.
" I have tested this with multiple Cloudstack versions, 4.15.0, 4.15.1,
4.15.2 and VMware, 6.5 and with 6.7 different patches and with the last
patches. I'm 100% that is related to these 2 servers, I do not understand what
is wrong with these servers, this is the problem.
We have 2 identical servers' hardware/ESXI, the only difference is the
location, the not working, are in UK, and any other location we have, DE, NYC,
FR, CA, etc. works fine. But we tested with the exact same servers which are
from DE(Germany) works perfect, with any ACS or VMware version (also same CIDR
range/size for public and private), when we test with UK, we get same error no
matter what."
I want to mention that we have these servers (UK, DE, FR, CA ) from OVH in
vRack and the UK, are not working. ( I manage these server for more than 5
years )"
Regards,
Cristian

Re: Unable to read/process CSR: Command failed due to Exception: java.lang.Exception
ok, than I would like to add an idea to your "it's the server". Not saying
you are wrong but location points to network i.e. firewall(s).
Hope you strike luck,

Thank You Alex for the information. I will take that into consideration.

Re: Recommendation for Storage.
Op 23-09-2021 om 12:18 schreef Mevludin Blazevic: Hi all, very interesting discussion here. I am facing the issue connecting my Ceph cluster with Cloudstack via the RBD protocol. It seems like there is either a documentation or software bug because we are running always in the same error (rbd pool not found). I was thinking about creating a NFS service on my Ceph cluster to connect it to Cloudstack because I know that adding an NFS server as primary storage works. My cluster is far smaller than yours but I am worry about performance and IOPS when using NFS service with Ceph. That is weird though. Ceph+RBD should just work with CloudStack. Using this with tens of thousands of VMs. NFS works fine as well. In our case we use TrueNAS M50 appliances in addition to Ceph for the use-cases where we need much lower latency. Both function fine with KVM.

Abishek, NFS over a bunch of drives works just fine but has no means for failover (out of the box, when self-built). If your benchmark shows enough IO performance per VM, then NFS is just the way to go. Keep in mind that NFS can have various backing store technologies like NetApp appliances, Ceph, plain RAID volumes - it leads to different performance levels and reliability guarantees.

KVM + iSCSI/FC
HI all! I try to configure CloudStack with KVM hypervisor and SAN storage. I CAN'T use NFS for some reasons. I have few questions: 1) Which is best solution to configure CS + KVM + SAN for newest CS versions (4.15.x)? In documentation I saw few possible solutions - CLVM, Shared Mountpoint and Gluster. Which of them is easiest for configure and have max performance for end users? 2) Maybe someone have actual manual or how-to for similar configuration?

Virtual Router failing health check - webserver.service
Hi everyone, I am setting up a redundant VPC. Therefore i created a custome service offering with the following Service provided by the virtual Router: - Portforwarding - Network ACL - SourceNAT - VPN - StaticNat I now getting alerts, that the router couldn't pass all health checks. The one failing at the moment is "webserver.service". As far as i got reading the log files, the apache service on the router is shutting down, as know valid / correct ssl - certificate is availeable. So now i am looking for some support on how to get rid of the errors and some information, why a webserver is running on the router? I found some articel in the wiki about the integrated Load Balancer. But i didn't have the service in the vpc service offering as well it wasn't selected for the (custome) service offering for the tier-networks for the vpc. Hope someone can help me out! Regards!
