Re: The CPU has been disabled by the guest operating system
So, what's in Log after you reboot the machine?
Re: The CPU has been disabled by the guest operating system
well, if u mean log in mikrotik CHR well there's nothing because i reset the CHR and before reset CHR is like freezing !! and on ESXi also nothing say and work again like nothing happend !! its realy confusing !
Re: The CPU has been disabled by the guest operating system
Is it what you think or what you saw?there's nothing because
Also, what version do you use?
Re: The CPU has been disabled by the guest operating system
for first time i used 6.39 and still the problem and before 2 days ago upgraded the routerOS to 6.42.6 and still same problem , and saw nothing in log !
Re: The CPU has been disabled by the guest operating system
anyone can help me !?
Re: The CPU has been disabled by the guest operating system
is it CHR not compatible with ESXi 6 ?
Re: The CPU has been disabled by the guest operating system
I don't know if it's your case, but I've seen CHR stopping when it didn't have enough memory. I originally had VMs with 128MB, but CHR got a little bit more hungry over the time.
Re: The CPU has been disabled by the guest operating system
CHR is certainly compatible with ESXi 6 and 6.5(u2).is it CHR not compatible with ESXi 6 ?
You must surely have some log files purporting to this?
Re: The CPU has been disabled by the guest operating system
well i don't have any problem with memory only cpu and disabled for unknown reason to me !! thanks for your answerI don't know if it's your case, but I've seen CHR stopping when it didn't have enough memory. I originally had VMs with 128MB, but CHR got a little bit more hungry over the time.
Re: The CPU has been disabled by the guest operating system
that's my real problem only that log the "The CPU has been disabled by the guest operating system" i have so and i don't know why cpu disabled !CHR is certainly compatible with ESXi 6 and 6.5(u2).is it CHR not compatible with ESXi 6 ?

Re: The CPU has been disabled by the guest operating system
When you say you have just installed CHR, do you mean you’ve used the premade OVA from MikroTik or you have used an ISO to install or how have you done it?
Googleing the problem refers you to the VMware help center and the general consensus is it is caused by a kernel panic in the guest.
So how have you deployed it?

Re: The CPU has been disabled by the guest operating system
deployed as OVA from mikortik ,is that effect on cpu and may be disable it ?When you say you have just installed CHR, do you mean you’ve used the premade OVA from MikroTik or you have used an ISO to install or how have you done it?

Re: The CPU has been disabled by the guest operating system
How many CPU's are you assigning to the CHR installation? What happens if you set just 1?
Re: The CPU has been disabled by the guest operating system
CPU is 32 and ram 8G ,i didn't try 1 CPU cause i have more than 1 Gbps trafficHow many CPU's are you assigning to the CHR installation? What happens if you set just 1?
Re: The CPU has been disabled by the guest operating system
ESXi on the free license will only allow up to 8 vCPUs, have you paid for ESXi? Usually ESXi would not start the VM and tell you to pay for it but maybe you’re getting a weird behaviour?
How many CPUs are you allocating?

Re: The CPU has been disabled by the guest operating system
If you run maybe 2 cores do any get disabled?
Re: The CPU has been disabled by the guest operating system
well i didn't try for 2 core ,i used to 32 core and get disabled don't know why and seems mikrotik also didn't have a solutions !If you run maybe 2 cores do any get disabled?
Re: The CPU has been disabled by the guest operating system
We are hit with the same problem: The CPU has been disabled by the guest operating system. 4 times in the last week or so.
Is there any way to get the kernel panic message?

Re: The CPU has been disabled by the guest operating system
Many do this and send to mikrotik. So they can troubleshoot.

Re: The CPU has been disabled by the guest operating system
I also face this problem for few last days. Chr 6.43.2 in vmware workstation with 1cpu /2cores in virtual host is once per day switched of because of this. At the moment I have removed one core hoping that the ros will not try to disable the last core it has.
Is there a ticket created at mikrotik for this? Has anyone got any response from support?

Re: The CPU has been disabled by the guest operating system
Same problem here on 6.42.9
1 gbps of traffic. ESXI 6.7 with vCenter.
2 Cores and 512mb of RAM
Any words from Mikrotik?
thanks

Re: The CPU has been disabled by the guest operating system
We've encountered this particular error message already with other VMs after kernel panics occurred. As a workaround, you could try to edit the CPUID mask settings and check if the CHR-VM might boot again: https://docs.vmware.com/en/VMware-vSphe ... 78CEA.html
Re: The CPU has been disabled by the guest operating system
Hi,
I am facing the same problem.
I set up the CHR router by following this guide: https://wiki.mikrotik.com/wiki/Manual:CHR .
I have a licensed VMware and a CHR with P1 license. After having used it for 4 days it freezed without showing any log. VMware only displayed "The CPU has been disabled by the guest operating system".
The CHR has 2 CPU, 4GB RAM and 4GB disk storage. 6.43.13 is the version of VMware disk image.
Did someone find any solution to this problem?
Have I set up the machine with wrong parameters?
Thanks

Re: The CPU has been disabled by the guest operating system
Guys, disable conn tracking and problem will gone.
It's been known for a long time. It dies once DDOS kicks in. They not fixed that, but I can confirm disabling conntracks not causing CPU to go offline and machine halt.

Re: The CPU has been disabled by the guest operating system
If disabling conn tracking will disable NAT, what kind of router is it??Guys, disable conn tracking and problem will gone.

Re: The CPU has been disabled by the guest operating system
A router without NAT is definitely not a home routerIf disabling conn tracking will disable NAT, what kind of router is it??

Re: The CPU has been disabled by the guest operating system
Hi,
I recommend taking a look at your vswitch and physical switch architecture. Be clear about your trunks and any spanning tree issues.
Try out the options with promiscuous mode on the vswitches, and esp on the physcial host interfaces.
Make sure to use VMXNET3 interfaces and drivers. Understand clearly about using vlan 4096 in esxi for trunk ports.
I have vsphere 6.5 with 6 CHRs doing BGP, OSPF IP Transit ipv4 and v6 and have NEVER seen this. We have been doing this since 2017.
Our routers are connected via ESXI trunks to external physical switches which we use as port extenders to the CHR, and then connect to Transit providers from there.
And yes, we have conntrack turned on, and we have also had to handle DDOS situations, but never seen the VM crash.
Also the IPArchitechs guys have run some big labs like this with 10g and I am not aware of them seeing the issue (correct me if Im wrong).
Salaams,
Alex
