Hello,

Thanks for your time reviewing and responding. I’m new to OpenNebula and I’m currently preforming and evaluation using minione with v6.10.0 for about 2 weeks now. Its been going very well so far. However, I’m having trouble testing one use-case where I select the specific host placement to launch the VM.

I’ve noticed two issues. Issue #1 I’ve worked around, but thought to mention it as possible bug. (as a new user it took me many hours to find the issue/workaround.)

6.10.0 Env to Create a NEW VM and Placement on a specific host.

- Sunstone web UI.
- 2 physical host (OnPrem) with Ubuntu22.04
- New setup, no other VMs on hosts
- If placement isn’t used then VMs are properly places across the 2 hosts. (so host memory, cpu, datastores all seem fine. (even testing with 3 VMs in one launch spreads them across the two host as expected.)
- Using Placement for “cluster” works fine too.
- The issues are only seen with selecting a specific HOST placement

**Issue#1 - using AppStore Ubuntu 20.04 template & selecting 1 HOST**

```
Web interface creates "host requirement expression" automatically as " & (HOST_ID = 20)"

```

This causes the following failure on launch:

Wed Oct 23 22:15:53 2024: Error in SCHED\_REQUIREMENTS: ‘(CLUSTER\_ID = 117) & !(PUBLIC\_CLOUD = YES) & !(PIN\_POLICY = PINNED) & ( & (HOST\_ID = 20) )’, error: syntax error, unexpected ‘&’, expecting ‘!’ or STRING or ‘(’ at line 1948281953, columns 73:74

The WORKAROUND is to change webUI “host requirement expression” to only “HOST\_ID = 20”

I then get further, but stuck at Issue#2

**Issue#2 using AppStore Ubuntu 20.04 template & selecting 1 HOST with workaround to issue#1**

Always fails with:  
Wed Oct 23 22:19:24 2024: Cannot dispatch VM: No host meets capacity and SCHED\_REQUIREMENTS: (CLUSTER\_ID = 117) & !(PUBLIC\_CLOUD = YES) & !(PIN\_POLICY = PINNED) & ( HOST\_ID = 20 )

I’ve spent better part of a day trying to find what I have setup wrong or doing wrong but can’t find it.

The 2 host are ON state. Zero VMs on both. In cluster 117. OnPrem KVM. No Pinning.

By default my host didn’t have attributes PUBLIC\_CLOUD or PIN\_POLICY. I assume not present would satisfy the “NOT”. I did explicitly add it to host 20, but that didn’t help. I have set scheduler logs to level 5 highest debug level. Still not explicit statement as to what is not matching the criteria to schedule on host.  
I tried adding also sorts of other policy statements etc, none helped.

I’ll tried to attached the scheduler log, but as new user to forum I’m blocked per upload error., but here is a clip. I can paste more if needed.  
I’ve listed onehost show 19 & 20 below too. (removing only ssh key info and full host name)

Hello,  
Please take a look at the following bold parts

> Wed Oct 23 21:50:22 2024 [Z0][SCHED][DD]: Host 20 discarded for VM 58. It does not fulfill SCHED\_REQUIREMENTS: (CLUSTER\_ID = 117) & !(PUBLIC\_CLOUD = YES) & !(PIN\_POLICY = PINNED) & ( ( **HYPERVISOR=undefined** ) & (HOST\_ID = 20) )

and

> root@opennebular-1:/etc/one# onehost show 20  
> …  
> **HYPERVISOR=“kvm”**  
> …  
> opennebular-1:/etc/one# onehost show 19  
> **HYPERVISOR=“kvm”**

So, you should select a hypervisor for the VM to be KVM for hosts matching to succeed or figure-out how to remove the hypervisor from the SCHED\_REQUIREMENTS

Hope this helps,  
Anton Todorov

Hi Anton,

Thanks for the prompt response! I thought I had only included the logs from the last run, but seems I pasted some older ones.

There is a 3rd WebUI issue I was leaving off; in some instances selecting a placment host the “host requirement expression” is automatically set to  
( ( **HYPERVISOR=undefined** ) & (HOST\_ID = 20) )

The first few times I missed it. Later in those tests I changed undefined to kvm manually at the web UI and the same issue came.

Here are complete/clean logs running again just now.

Hello Ken,

This is the summary I’ve extracted from the logs:

```auto
Thu Oct 24 13:30:51 2024 [Z0][HOST][D]: Discovered Hosts (enabled):
ID : 19 -> HOST_ID
CLUSTER_ID : 117
PUBLIC : 0
...
ID : 20 -> HOST_ID
CLUSTER_ID : 117
PUBLIC : 0

HOST 20 INFORMATION
ID : 20
NAME : s002-m5-40g-kvm27
CLUSTER : onprem-cluster-laas-1a
HYPERVISOR="kvm"
PIN_POLICY="NONE"
PUBLIC_CLOUD="NO"

HOST 19 INFORMATION
ID : 19
NAME : s002-m5-40g-kvm38
CLUSTER : onprem-cluster-laas-1a
HYPERVISOR="kvm"

```

According to the requirements, host 19 should be discarded due to `HOST_ID = 20`  
But indeed there is no excuse why host 20 is not selected.  
Could you clarify that the host `CLUSTER_ID = 117`, by looking at the output of `onehost show -x 20`? I am assuming that `onprem-cluster-laas-1a` is cluster 117…

But in that case, I have no idea what sched requirements are not fillfuled for host 20 😕 (HOST\_ID - check, HYPERVISOR - check, not PIN\_POLICY - check, not PUBLIC CLOUD - check, CLUSTER\_ID - check…)

Best Regards,  
Anton Todorov

Hi Anton,

Thanks once again for the prompt response. Yes host 20 is part off cluster 117.  
Here is the xml.

\<CLUSTER\_ID\>117\</CLUSTER\_ID\>  
onprem-cluster-laas-1a

Any suggestions what I can do to debug further? Any other service I should increase the log level to get info that’s being sent to the scheduler process? (or something like that.)

After some significant debugging and reviewing the Scheduler.cc code I found the issue/WebUI bug.

This works: (HYPERVISOR=kvm) & (ID = 20)  
WebUI give this by default: (HYPERVISOR=undefined) & (HOST\_ID = 20)  
It was somewhat obvious to change “undefined” to “kvm” but the HOST ID… well that took a few days to figure out.

=== Debugging Details

Workaround # was to put HOST\_ID as an attribute on each host, but that wasn’t the best fix.

The HOST have an “ID” value, but needed to have “HOST\_ID” value (I thought). I had to add the attribute to each host manually. I assumed was a bug? Maybe previous release had HOST\_ID in the XML where it is only ID now?

Reviewing the scheduler code I was failing at this point:

logs:

```auto
Wed Oct 30 18:51:47 2024 [Z0][SCHED][DD]: Setting VM groups placement constraints. Total time: 0.00s
Wed Oct 30 18:51:47 2024 [Z0][SCHED][DD]: Host 19 discarded for VM 109. It does not fulfill SCHED_REQUIREMENTS: (CLUSTER_ID = 117) & !(PUBLIC_CLOUD = YES) & !(PIN_POLICY = PINNED) & ( (HYPERVISOR=kvm) & (HOST_ID = 20) )
Wed Oct 30 18:51:47 2024 [Z0][SCHED][DD]: Host 20 discarded for VM 109. It does not fulfill SCHED_REQUIREMENTS: (CLUSTER_ID = 117) & !(PUBLIC_CLOUD = YES) & !(PIN_POLICY = PINNED) & ( (HYPERVISOR=kvm) & (HOST_ID = 20) )
Wed Oct 30 18:51:47 2024 [Z0][SCHED][D]: Match-making results for VM 109:
        Cannot schedule VM, there is no suitable host.

```

Tracing the code I’m at this point and failing the simple bool statement:

```auto
static bool match_host

        if ( host->eval_bool(vm->get_requirements(), matched, &estr) != 0 )
        {
            ostringstream oss;

            n_error++;

            oss << "Error in SCHED_REQUIREMENTS: '" << vm->get_requirements()
                << "', error: " << estr;

            vm->log(oss.str());

            error = oss.str();

            free(estr);

            return false;
        }

        if (matched == false)
        {
            error = "It does not fulfill SCHED_REQUIREMENTS: " +
                    vm->get_requirements();
            return false;
        }
    }

```

get\_requirements() is this: (CLUSTER\_ID = 117) & !(PUBLIC\_CLOUD = YES) & !(PIN\_POLICY = PINNED) & ( (HYPERVISOR=kvm) & (HOST\_ID = 20) )

I then started manually adding attributes to each host until finding out that the one that mattered was HOST\_ID. PUBLIC\_CLOUD and PIN\_POLICY there or not did not matter.

CLUSTER\_ID is in the host xml already, but HOST\_ID is NOT. Its there as “ID”.  
This explains why all other use-case work as they trigger off the Cluster ID or Default cluster. This one use-case needs the HOST\_ID to match.

```auto
oneadmin@opennebular-1:/var/log/one$ onehost show -x s002-m5-40g-kvm27.mitg-bxb300.cisco.com | grep HOST_ID
oneadmin@opennebular-1:/var/log/one$ onehost show -x s002-m5-40g-kvm27.mitg-bxb300.cisco.com | grep ID
  <ID>20</ID>
  <CLUSTER_ID>117</CLUSTER_ID>

```

Then as writing this realized… what If I just change the sandstone auto-filled in value to ID instead of HOST\_ID… That worked!!! So I guess the bug is the WebUI is giving a bad example?

This works: (HYPERVISOR=kvm) & (ID = 20)  
WebUI give this by default: (HYPERVISOR=undefined) & (HOST\_ID = 20)  
It was somewhat obvious to change “undefined” to “kvm” but the HOST ID… well that took a fee days to figure out.

Hi Can someone from OpenNebula confirm if this issue is already addressed or not in next release? If not, I’d be happy to add the github bug case.

Note, at least two other “new” users in last week have hit this too.

[Cannot dispatch VM: No host meets capacity and sched\_requirements - Community Support - OpenNebula Community Forum](https://forum.opennebula.io/t/cannot-dispatch-vm-no-host-meets-capacity-and-sched-requirements/13377/7)

I added this github bug report for this issue:

> <https://github.com/OpenNebula/one/issues/6834>
>
> \*\*Description\*\*
> Sunstone Interface for launching a new VM and selection a clust…er or Host \*\*Placement\*\* sets two bad variables in "Host requirements expression".
> 
> Selecting a Cluster gives: (HYPERVISOR=undefined)
> Selecting a Host gives: (HYPERVISOR=undefined) & (HOST\_ID = 20)
> 
> HYPERVISOR=undefined is somewhat obvious and most user figure out to change that to "KVM" for example. 
> However HOST\_ID will cost you a few days of confusion. It needs to be ID. Only that will work. 
> 
> \*\*To Reproduce\*\*
> Launch a VM and attempt to select a particular host to force it to be scheduled on that host.

> \*\*Expected behavior\*\*
> I expect the UI to set "Host requirements expression" properly for selected Host or cluster's HYPERVISOR type and ID variable should be correct.
