RE: VM console keeps pausing to the point of being unusable
This bug is making cloudstack completely unusable
Is there a way to test VNC directly on KVM?
Thanks

Hi Nicolas,
It was persisting over console systemVM destroy and creation, and any instance over 3 KVM hosts.
Annoying we did not see the error in the console VM logs yesterday and users are reporting the console is currently working ok.
Kind Regards
Adam

Hi Adam,
That's an error I've never hit before, does the issue persist after destroying and recreating the console proxy VM?
Regards,

Hello,
We have an annoying issue, when using the cloudstack console to access a running instance the viewer will keep pausing every 10 to 15 mins, then its fine for a bit.
I have found the cloud.log from the console proxy which is showing java exceptions queue full, could this be related?

Any help appreciated
Thanks

Re: VM console keeps pausing to the point of being unusable
Posted by Andrija Panic <an...@gmail.com>.
Are you using SSL? If so, can you temporarily turn it off (
consoleproxy.sslEnabled = false in global settings) - this is a good way to
eliminate SSL-caused issues (if any)
Best,

RE: VM console keeps pausing to the point of being unusable
Posted by Adam Witwicki <aw...@oakfordis.com>.

Adam,
did you try accessing the VM console via standalone VNC viewer, based on the way Rohit explained - dump the XML of the VM, check the IP/port and password details - and use those to access <KVM-host-IP:port> and see if that connections is established quick enough.

Re: VM console keeps pausing to the point of being unusable

Adam,

Adam,
did you try accessing the VM console via standalone VNC viewer, based on
the way Rohit explained - dump the XML of the VM, check the IP/port and
password details - and use those to access <KVM-host-IP:port> and see if
that connections is established quick enough.

RE: VM console keeps pausing to the point of being unusable

Am I able to get some help with this?
Cloudstack really is unusable
Is it related to the speed issues with SSL?
Thanks

Rohit, sorry the long delay
Yes all servers and VMs are in time sync.
It does seem to be an issue with the console proxy, no attempt of increasing its resources is improving the situation.
What else can we try?

Hi Adam - can you check and sync time on your KVM hosts, management servers and CPVM using ntp? This is because SSL-enabled connection are time sensitive.
In order to test VNC directly, you can ssh into the host and do something like:
# virsh list # find the VM
Then run dumpxml and grab the IP/port and password, for example:
# virsh dumpxml --security-info s-180-VM | grep vnc
<graphics type='vnc' port='5901' autoport='yes' listen='192.168.1.10' passwd='_u6LayCdnCrr_JuUwCrq2A'>
If you're on the management network, you can use any VNC client and details you find to connect to the VNC directly. I often connect virt-manager (UI) to a KVM host over SSH and use the console directly (the only trick is to grab the password, by clicking the information tab -> go to VNC -> click on show password -> copy and use it to see console).
Regards.

I agree, try checking the number of concurrent connections as well as increasing the CPVM capacity.
Also check the network for any glitches / lag between the CPVM and the KVM hosts ________________________________

Do you know how many concurrent access to VNC from your user ?
Or you want to increase the Console Proxy Capacity?
Also, please make sure the console proxy Ip/Network is up when you having issue on it.

Re: VM console keeps pausing to the point of being unusable
Posted by Andrija Panic <an...@gmail.com>.
Adam,
did you try accessing the VM console via standalone VNC viewer, based on
the way Rohit explained - dump the XML of the VM, check the IP/port and
password details - and use those to access <KVM-host-IP:port> and see if
that connections is established quick enough.
Best,

Forgive me if I am wrong
But this is where the exception lies https://github.com/apache/cloudstack/blob/64f792bd7c3a2017d760b0d47b9a403cb88bab99/services/console-proxy/server/src/main/java/com/cloud/consoleproxy/vnc/VncClientPacketSender.java#L42
private final BlockingQueue<ClientPacket> queue = new ArrayBlockingQueue<ClientPacket>(30);
I guess I need to understand why objects are not leaving the queue?

Rohit, sorry the long delay
Yes all servers and VMs are in time sync.
It does seem to be an issue with the console proxy, no attempt of increasing its resources is improving the situation.
What else can we try?

Hi Adam - can you check and sync time on your KVM hosts, management servers and CPVM using ntp? This is because SSL-enabled connection are time sensitive.
In order to test VNC directly, you can ssh into the host and do something like:
# virsh list # find the VM
Then run dumpxml and grab the IP/port and password, for example:
# virsh dumpxml --security-info s-180-VM | grep vnc
<graphics type='vnc' port='5901' autoport='yes' listen='192.168.1.10' passwd='_u6LayCdnCrr_JuUwCrq2A'>
If you're on the management network, you can use any VNC client and details you find to connect to the VNC directly. I often connect virt-manager (UI) to a KVM host over SSH and use the console directly (the only trick is to grab the password, by clicking the information tab -> go to VNC -> click on show password -> copy and use it to see console).
Regards.

Do you know how many concurrent access to VNC from your user ?
Or you want to increase the Console Proxy Capacity?
Also, please make sure the console proxy Ip/Network is up when you having issue on it.

RE: VM console keeps pausing to the point of being unusable
Posted by Adam Witwicki <aw...@oakfordis.com>.
Rohit, sorry the long delay
Yes all servers and VMs are in time sync.
It does seem to be an issue with the console proxy, no attempt of increasing its resources is improving the situation.
What else can we try?
Thanks
Adam

Hi Adam - can you check and sync time on your KVM hosts, management servers and CPVM using ntp? This is because SSL-enabled connection are time sensitive.
In order to test VNC directly, you can ssh into the host and do something like:
# virsh list # find the VM
Then run dumpxml and grab the IP/port and password, for example:
# virsh dumpxml --security-info s-180-VM | grep vnc
<graphics type='vnc' port='5901' autoport='yes' listen='192.168.1.10' passwd='_u6LayCdnCrr_JuUwCrq2A'>
If you're on the management network, you can use any VNC client and details you find to connect to the VNC directly. I often connect virt-manager (UI) to a KVM host over SSH and use the console directly (the only trick is to grab the password, by clicking the information tab -> go to VNC -> click on show password -> copy and use it to see console).
Regards.

Also, please make sure the console proxy Ip/Network is up when you having issue on it.
