I have run a test on cosmic. The test involved MAAS 2.4.3 installed on bionic on 3 of the blades of the UCS chassis in the customer's data center. I installed cosmic, 18.10 on a 4th blade and installed libvirt and qemu-kvm and defined a VM similar to how maas defines VMs. with this xml: https://pastebin.ubuntu.com/p/yCTRGDjx2H/
$ lsb_release -d Description: Ubuntu 18.10 The ipxe-qemu version installed from dist is: 1.0.0+git-20180124.fbe8c52d-0ubuntu4 The attached screenshot is of the failed pxe boot of the testipxe vm. Added the ppa:andreserl/maas apt repo and installed ipxe-qemu which gave me version: 1.0.0+git-20180124.fbe8c52d-0ubuntu2.2~18.04.1 Note that I had to edit /etc/apt/sources.list.d/andreserl-ubuntu-maas- cosmic.list replacing "cosmic" with "bionic" because that repo doesn't have cosmic packages. And then I had to downgrade the ipxe-qemu because the cosmic version is greater than the one in the fix repo: # apt install ipxe-qemu=1.0.0+git-20180124.fbe8c52d- 0ubuntu2.2~18.04.1 Once I jumped through those hoops, I booted the exact same testipxe vm that failed to pxe boot above and it succeeded in getting an IP and commission in MAAS. ** Attachment added: "screenshot of failed boot" https://bugs.launchpad.net/maas/+bug/1805920/+attachment/5228521/+files/Screen%20Shot%202019-01-11%20at%207.36.20%20PM.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1805920 Title: iPXE ignores vlan 0 traffic To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1805920/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
