Cannot set up guest memory error DO407 chapter 12

Latest response

When doing the guided exercise I get the following error...

```
[root@tower webapp]# vagrant up
Bringing machine 'default' up with 'libvirt' provider...
==> default: Starting domain.
There was an error talking to Libvirt. The error message is shown
below:

Call to virDomainCreateWithFlags failed: internal error: qemu unexpectedly closed the monitor: Cannot set up guest memory 'pc.ram': Cannot allocate memory
```

Looking this error up says that I don't have enough RAM.

Sure enough, I don't

[root@tower webapp]# free -m
total used free shared buff/cache available
Mem: 1839 1216 144 38 478 375
Swap: 0 0 0

Anyway to get more ram? or at least NOT run VMs on the same machine you're running Tower with postgres?

Hi Christian Hernandez,

Sorry you're having trouble with your lab. You might not be aware of this, your Red Hat Learning Subscription is a supported product. I recommend you submit a case with Red Hat. Community support may not be the best avenue to get your issue resolved.

  • Go to this link: https://access.redhat.com/support/cases/, which is at the top of this page too, named SUPPORT CASES.
  • In the Product drop down, select: Red Hat Online Learning (NOTE: You will need to scroll down through a list in the drop-down menu)
  • Important, in the Product Version drop down, select the largest number (as I type this, it is 1.0, but that may change over time) NOTE: the "Submit" button won't activate until this is selected.
  • In the Case Type drop down, select: Other
  • In the Problem Statement block, enter something concise, the course number, and a small description.
  • In the Case Description block, enter the specifics.

The other blocks are straightforward enough. When I've submitted a ticket for Red Hat Online Learning, I make it a low priority, it certainly is not production. One of the course administrators does on occasion check the forum, but you ought to submit a ticket for this issue since this is supported.

The Training Principal Product Manager also highly recommends submitting a case for this, as the experiences of one customer in resolution may not necessarily work with another (paraphrasing) see this link, it leads to his comments Also examine the Red Hat course updates page at https://access.redhat.com/discussions/3344631. for up to the date info they post.

Regards,

RJ
