Thanks Rohit,
Those are the articles I'm basing my ideas on as well, looks like the only 
available alternative is passthrough, with it's limitations.

Am wondering if anyone out there is actually running this in production.

Hi Alex,

I've heard/seen some users using GPUs with XenServer for graphical rendering 
and I remember somebody discussing about GPU in KVM which is possible by using 
the extraconfig feature while deploying VM (the only limitation is on KVM you 
cannot share one GPU across VMs; however if your server has multiple GPUs you 
can assign them to one or more VMs).

Hi all!
I have same question.
I can scale only CPU but not RAM.

In Global Settings:
enable.dynamic.scale.vm - true
scale.retry - 2

In template:
Dynamically Scalable - Yes

XCP tools is installed.

If you got till here I believe you have already enabled global setting and 
marked the template as dynamically scalable.

Please check if host license supports dynamic scaling or not. In the host 
license view on xenserver you can check that using "restrict_dmc" flag. If it 
is set to true then dynamic scaling cannot be done on VM.

If it is false, then other thing you can check is "guest_os_details" table for 
"xenserver.dynamicMin" and "xenserver.dynamicMax" under the guest OS id used in 
the template. If entries are not there try using a different template having 
these entries or insert recommended values for that OS.

Re: [DISCUSS] VMware network rate for network and VMs

[Abhishek Kumar]

Hi Vivek,

Thank you for your response.
I understand the scenarios you have explained but the issue I face right now is 
that portgroup for user VMs is not updated when network offering (with network 
rate difference) for that network is changed from ACS.
I tried to show that here, https://youtu.be/Kdaad9c1Fq4

I've also gone through the code and on network offering change, currently ACS 
just stops and destroys the running VR, creates a new portgroup (for new 
network rate) and starts new VR on that portgroup. And user VMs continue 
running on the existing portgroup.

Similarly, for different NICs of the VM, it can have different network rate 
depending on default and non-default NIC.
eg:
VM, v1 is created with a compute offering having network rate, 350Mbps
It has three networks:
n1 with network offering having network rate 400Mbps (default NIC)
n2 with network offering having network rate 500Mbps
n3 with network offering having no rate specified, defaulted to 
"network.throttling.rate" 200Mbps. "vm.network.throttling.rate" is set to 
375Mbps

Now, three nics of the VM will have portgroups with following network rates:
NIC1 (default) - 350Mbps (taken from compute offering)
NIC2 - 500Mbps (taken from n/w offering)
NIC3 - 200Mbps(taken from n/w offering)

Therefore, my point is both network rate from compute offering and value of 
vm.network.throttling.rate doesn't affect all the NICs of the VM and are 
honored just by the default NIC.

Regards,
Abhishek

Hello Abhishek,

Everything is useful and it completely depends on your requirements..!

  *   Is having VM-level (using compute offering and global setting for
VMs) useful? Having a higher network rate for VMs and a lower network rate
for VRs(network) will make it useless.

Ans - Yes definitely it's useful, so consider a scenerio where you want to
provide a higher speed of data transfer between VMs in same network  (
Guest traffic ) but lower speed for public traffic or may be on the
different network.


  *   Should there be a single portgroup in vCenter based on the network
rate of VRs/network especially in the case when the network rate for VRs is
lower?

Ans -  ACS create separate port group for each config, single port groups
can't controller multiple QoS. So let's suppose if you create a VM with 500
Mbps network rate, ACS will create a port group and will put 500Mbps in
network rate, so if you create other VMs under the same network and same
compute offering it will out under the same, but the moment you change your
network offering i.e 200 Mbps then it will create a separate port group
with 200 Mbps network rate and will attach same to the VM.


  *   Even while using different network rates, should there be consistency
across different NICs of user VMs? Currently, compute offering and global
setting only affects the default NIC of the user VMs.

Ans- As I said, it create separate port group as per the network rate and
VLAN.

Re: implement an authentication challenge method (such as Recaptcha) in the CloudStack UI

[Rohit Yadav]

Hi Ahmed,

We have a feature to restrict no. of user logins before the user is 
locked/disabled via the global setting incorrect.login.attempts.allowed. If 
you've comfortable with frontend programming, you can extend the VueJS based UI 
to implement/add the recaptcha solution (send a PR too!).

In addition, we've a feature to limit API calls by a user that I've not tested 
but according to codebase there are these settings available to configure it: 
api.throttling.max, api.throttling.enabled, api.throttling.interval and 
api.throttling.cachesize - kindly test if it's useful for your use-case.

CloudStack lacks a general-purpose  2FA framework (backend/frontend or both), 
however, off-the-shelf 3rd party solutions do exist for bot-defence. For 
example, Cloudflare has a reverse-proxy based solution 
https://www.cloudflare.com/products/bot-management/ The way it works is that 
you use the Cloudflare DNS and enable option to proxy via CloudFlare, which 
will prompt spammers/bots/malicious users to show a captcha or human check 
(some puzzle or human challenge like select pics that have bikes etc) and if 
they only pass they'll be allowed to use the resource (i.e. the website url). 
You may experiment with solutions too as an immediate fix.

Regarding ReCAPTCHA function it self it is simple , It’s just a standard script

[DISCUSS] VMware network rate for network and VMs

[Abhishek Kumar]

Hi all,

I've been working on fixing/refactoring VMware portgroup reconfigure on network 
offering change, https://github.com/apache/cloudstack/pull/5181
While working on it I found different portgroups on the same VLAN can be used 
based on the different network rates used in the network offering of the 
network and compute offering of the user VMs. Below are my findings:

  *   Network offerings will control network rate only for VR(s) and 
non-default NICs of the user VMs.
  *   Default network rate for VRs and non-default NICs of the user VMs can be 
controlled by global setting, "network.throttling.rate".

  *   For the default NIC of user VMs, the network rate is controlled by the 
compute offerings of the VM.

  *   For the default NIC of user VMs, the default network rate can be 
controlled using the global setting,"vm.network.throttling.rate".

So now my queries are:

  *   Is having VM-level (using compute offering and global setting for VMs) 
useful? Having a higher network rate for VMs and a lower network rate for 
VRs(network) will make it useless.
  *   Should there be a single portgroup in vCenter based on the network rate 
of VRs/network especially in the case when the network rate for VRs is lower?
  *   Even while using different network rates, should there be consistency 
across different NICs of user VMs? Currently, compute offering and global 
setting only affects the default NIC of the user VMs.

Please share your thoughts and ideas. It will be interesting to know how others 
configure network throttling for networks and VMs.

Re: cloudstack-sysvmadm access to 8096

Hi Wei,

Thanks for this. I still have it.

I initially upgraded from 4.15 to 4.15.1 but it failed as I didn't have the 
template. I downgraded back to 4.15 and first noticed then. I had the 404 
screen (as shown in your bug thread).

I re upgraded back to 4.15.1 but still have it. Not the 404 screen but the 
error x for input string: " ", an no hosts listed

I tried to change the Locale (as suggested) to en_US.UTF-8

(it was en-GB)

but I still get the error.

Thanks

Brian

Thanks Wei,


I have now managed to register the 4.15.1 template, re upgraded and ran

the cloudstack-sysvmadm scripts

remembering to set the API port back to 0


All seems ok except I still can't see any hosts listed under

infrastructure.


I don't get a 404 screen any more but no hosts listed and a x for input

string " " error

Hi Wei,



apt installed back to 4.15.0 versions



I seem now to have a problem registering the new systemvm template



I am using KVM, fill in the template for new url download as per

instruction, but appears to be a problem downloading 'Ready false'



Is there a way of force trying again?, I can't seem to delete it



Also, I appear to have lost my hosts list, they are running but the

infrastructure hosts page shows a '404 error' and 'Request Failed (431) For

input string " "'



Thanks very much for your help



Brian

Re: [RESULT][VOTE] New life to Terraform Provider CloudStack with Apache CloudStack project

[Harikrishna Patnala]

That's great to know and thanks for all the efforts Rohit.

For release management, I would like to volunteer myself for the RM. I'll 
create the first milestone and propose myself as RM on the mailing list.

Harikrishna

All,

The IP clearance process has finally passed 
(https://github.com/apache/cloudstack/issues/5159) and codebase have been 
imported:
https://github.com/apache/cloudstack-terraform-provider
https://github.com/apache/cloudstack-go

As an immediate next step, we need:

  *   Minimal changes/fixes to work towards its first release and publication 
to Terraform registry for users to use (any RM volunteers?)
  *   I'll request ASF infra to enable Travis and Github issues on these repos.

Regards.

Update - the process has been slow due to getting major contributors to agree 
on code base relicensing and getting Hashicorp to transfer the repo to its 
original/major author Sander who now has relicensed the repositories under 
APLv2:
https://github.com/xanzy/terraform-provider-cloudstack
https://github.com/xanzy/go-cloudstack

We're in the final process of IP clearance post which the code base will be 
accepted and available in the following repositories by either a ASF member 
(Paul has volunteered) or an officer of PMC with suitable permissions:
https://github.com/apache/cloudstack-terraform-provider
https://github.com/apache/cloudstack-go

As some may realise there is a new dependency repo (the Go SDK repo) which I'm 
advised by Sander should go along with the donation as it's used by the 
Terraform repo and Sander has notified submission of software grants 
(https://www.apache.org/licenses/contributor-agreements.html#grants) for both 
the repos. I'll keep the thread open if anyone has any concerns or objections

Re: Memory and CPU Failure

[Vivek Kumar]

Hello Abhishek,

When you enable HA on your compute offering, CS will try to restart the VMs on 
other available hosts as part of HA if any host goes down due to any unplanned 
issue.  You will also need to enable HA on your hypervisor side as well.  This 
will only work if your host goes down ( most of the time in case of hardware 
failure, host usually go down if host continues to run the CS may not restart 
or migrate the VM, so it’s better to set alerts on hardware failure, so that 
you move your workload before host goes down ).



Regards,
Vivek Kumar

Re: Limit Host Resource.

[Vivek Kumar]

Hello Abhishek, 

You can achieve n+1 redundancy  by putting limits on cluster level, Below are 
the few settings which you can set on cluster level and global level as well. 
So let’s say you have 4 host, then you can set limit on 70% for maintaining the 
n+1 redundancy.

cluster.cpu.allocated.capacity.disablethreshold
cluster.cpu.allocated.capacity.notificationthreshold
cluster.memory.allocated.capacity.disablethreshold
cluster.memory.allocated.capacity.notificationthreshold


Regards,
Vivek Kumar
