Backport KVM bug fix for nested KVM in ESXi and Hyper-V
by Gianluca Cecchi 16 Oct '18

16 Oct '18

Hello, I send a dedicated subject message on this topic. Also, the reply to my other related message seems not visible inside list archive page for some reason. It seems this nasty problem in nested virt using pc-i440fx-rhel7.X.0 machine type with X >= 3 impacts not only vSphere as main hypervisor for nested KVM, but other hypervisors too (Hyper-V) and other machine types too and could be due to a bug in KVM, so in the kernel, if I understood correctly. According to this link below https://bugs.launchpad.net/qemu/+bug/1636217 and its comment by Roman Kagan in June this year: " This is a KVM bug. It has been fixed in mainstream Linux in commit d391f1207067268261add0485f0f34503539c5b0 Author: Vitaly Kuznetsov <email address hidden> Date: Thu Jan 25 16:37:07 2018 +0100 x86/kvm/vmx: do not use vm-exit instruction length for fast MMIO when running nested I was investigating an issue with seabios >= 1.10 which stopped working for nested KVM on Hyper-V. The problem appears to be in handle_ept_violation() function: when we do fast mmio we need to skip the instruction so we do kvm_skip_emulated_instruction(). This, however, depends on VM_EXIT_INSTRUCTION_LEN field being set correctly in VMCS. However, this is not the case. Intel's manual doesn't mandate VM_EXIT_INSTRUCTION_LEN to be set when EPT MISCONFIG occurs. While on real hardware it was observed to be set, some hypervisors follow the spec and don't set it; we end up advancing IP with some random value. I checked with Microsoft and they confirmed they don't fill VM_EXIT_INSTRUCTION_LEN on EPT MISCONFIG. Fix the issue by doing instruction skip through emulator when running nested.

Tsirkin <email address hidden> Signed-off-by: Radim Krčmář <email address hidden> Although the commit mentions Hyper-V as L0 hypervisor, the same problem pertains to ESXi. The commit is included in v4.16. " Is it possible to backport the fix to the kernel provided by plain RHEL/CentOS hosts and/or RHVH/ovirt-ng nodes? Thanks, Gianluca

custom emulated machine in L2 ESXi
by Gianluca Cecchi 16 Oct '18

16 Oct '18

Hello, I had similar problem in the past with ESXi 6.0 U2 host where I defined a VM and used it as oVirt node for nested virtualization. If I run on this "virtual" node an L2 VM all went well until custom emulated machine value was at "pc-i440fx-rhel7.2.0". At some point the default became 7.3 and the L2 VM was not able to boot any more: it remained in blank screen at boot. The same up to now in 4.2.6.1 where this default seems to be 7.5 I'm having same problem in a mini lab on a nuc6 where I have ESXi 6.7 installed and try to setup an hosted engine environment. This problem prevents me to configure the hosted engine because the L2 VM that should be the hosted engine freezes (?) during its first startup and I see indeed that the qemu-kvm process is started with option "-machine pc-i440fx-rhel7.5.0" Being stated that I'm in an unsupported configuration, I would like to understand if I can correct in some point and proceed. So some questions: 1) How can I understand what is the difference between running qemu-kvm with "-machine pc-i440fx-rhel7.2.0" ad "-machine pc-i440fx-rhel7.5.0" so that I can then dig with ESXi parameters eventually to tune the settings of its VM that becomes my oVirt hypervisor? 2) Do I have any chance to configure my oVirt node so that when it runs the hosted-engine deploy it runs the engine VM with 7.2 parameter? Any conf file on host where I can somehow force 7.2 compatibility or set it as default? 3) during gluster base hosted-engine deployment at first "local" startup how can I connect to the console of the hosted engine VM and see where it is blocked? Thanks in advance, Gianluca

4.2 User Portal
by Стаценко Константин Юрьевич 16 Oct '18

Hello! Users cannot edit and expand VM’s disks from the User Portal after 4.2 upgrade anymore. VM UI screenshot attached. Users can press Edit icon, but only “Editing” appears and nothing more. Same thing happens under admin’s accounts on User Portal. From Admin Portal everything is fine. How can we fix this issue, so users can edit they VM from the User Portal as it was in 4.1 ? Thanks.

JIra upgraded, all other Atlassian apps now broken
by Soujanya Bargavi 15 Oct '18

15 Oct '18

I got a notice that our Atlassian Jira 7.1 introduce was EOL, and I should refresh. I read the particular refresh rules, (for example, making a reinforcement of the database). In any case, the procedure was a total fiasco which required two server reboots to get it settled - the overhaul notes neglected to say that the Postgres database ought to be refreshed past 9.1, while Debian 8 stays on 9.1. I think I recuperated the framework. Jira discovers its introduce dir once more, it discovers its home catalog once more, it discovers its database once more (counting our issues and essentially, our usernames and passwords). Regardless I have to physically begin it, as the init content doesn't work. In any case, I don't surmise that is the issue. Presently while we can sign in to Jira once more, there's a little issue. We had connected FishEye, Crucible, Bamboo and Confluence to Jira. In Jira I can see that I am as yet an individual from bamboo-administrator and intersection heads. With the goal that bit looks half OK, FishEye/Crucible is absent. Be that as it may, the "Application Links" for all connected applications are broken, and I can't sign in to any of those. There appear to be 2 related issues: On account of FishEye/Crubile, there are 5 clients characterized, out of the 10 we have in Jira. Those simply happen to be non-administrator accounts. Most are from representatives that left, and those records are obviously crippled in Jira. Subsequently, I can't sign in any longer. Also, I can't include myself (Starter Edition restrain). On account of Bamboo and Crucible, I can't sign in either. The Starter Edition restrict is the 10 clients, same as Jira https://goo.gl/bwWJRi, so this can't be indistinguishable issue from FishEye/Crucible. Bu I can't see which clients are known to Bamboo promotion Crucible without signing in. Bamboo shows that are robotized fabricates are as yet running, so it too approaches its database. A snappy psql to be sure demonstrates all databases to be available. Also, Bamboo's USERS table contains ONLY bamboo-administrator, while Jira demonstrates me as an individual from bamboo-administrator. My doubt, yet that is just a hunch, is this is identified with some "OAuth" setting for application connecting. There is an "Investigate" interface on the connected application page, however it just gives "OAuth investigating guide - Page Not Found" I do have root access to the Linux have, so I can settle things from the order line. What do I have to do to re-empower logins to the connected applications given that I can't login to them specifically?

Monkey script for copying VM/Host IP address
by rhrazdil＠redhat.com 15 Oct '18

15 Oct '18

Hello guys, I created a simple [Grease, Tamper, Violent, ...]Monkey script that copies IP address from clicked element on a page [0]. I believe it may be useful for anyone who often needs to copy IP addresses of Hosts/VMs from Ovirt and SSH to them. To use it, just copy-paste the script to your favourite *Monkey extension or create a new script and use: // @require https://raw.githubusercontent.com/rhrazdil/MonkeyScripts/master/cfme.js to get any future updates. At this point, it doesn't do more than just copying an IPv4 address, but if you have some more ideas, don't hesitate to let me know :). [0] https://github.com/rhrazdil/MonkeyScripts/blob/master/ipcopy.js Have a great day, Radim.

VM clone network interfaces names changes
by Artem Tambovskiy 14 Oct '18

14 Oct '18

Hello, I have a question indirectly related to oVirt - I have a VM with CentOS 6 running on my cluster, which has 6 virtual interfaces (eth0 - eth5). Now its a time to do an upgrade to CentOS 7 based, and I did a VM clone to test an upgrade process and was a bit surprised to see that now I have interface names shifted eth6 - eth11. I would afraid that I'll run out of digits soon :) Anyway how to change the interfaces names back to originals and perhaps prevent them form the further changes? I do understand that MAC address has changed, but don't get why it changing the interfaces names. Cleaning up everything from /etc/udev/rules.d/70-persistent-net.rules doesn't really helped .. Regards, Artem

Downloading a disk image
by Kristian Petersen 12 Oct '18

12 Oct '18

I am trying to download a disk that I have on my oVirt cluster. When I go into the Disks section of the web UI, I can click on it then click on Download, but it never seems to actually download anything. I left it overnight to see if it was just slow, but then nothing seemed to download at all. It just seemed stuck where it was after clicking download the day before. -- Kristian Petersen System Administrator BYU Dept. of Chemistry and Biochemistry

How Many Logical networks supported
by p.staniforth＠leedsbeckett.ac.uk 12 Oct '18

12 Oct '18

Hello, We are currently using oVirt for teaching and one of our requirements is for security such as IR PEN testing etc. We would like to create individual logical networks with a network profile that includes port mirroring, this is to reduce the amount of traffic they can see and the targets available. We are looking to to add VMs into Affinity Groups so they will run on the same host to make the port-mirror work but don't no if there is a limit on the number of logical networks that is allowed/practical. Thanks, Regards, Paul S.

Adding a new Host to Cluster via oVirt Manager fails with "No Route to Host"
by Markus Frei 12 Oct '18

12 Oct '18

Hello everybody I am facing the following issue currently. I am trying to add a new physical host to our cluster via oVirt Management Engine Web GUI. Apparently communication between oVirt Engine and the corresponding host is working well, since all necessary packages will be installed successfully. But after a while the installation process fails with the error "No Route to Host" and the host ends up in state "non operational". I checked the network interfaces via Web GUI (Host -> Network Interfaces -> Setup Host Networks) and none of the interfaces are present. In my opinion this is the main problem. It seems the interfaces are not being recognized. I tried using a bond interface and a single interface with static configuration (IP, DNS, Gateway). None of them worked. Further Log Errors: WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (EE-ManagedThreadFactory-engine-Thread-1688) [] Host 'HOSTNAME' is not responding.
