Outside of the initial topic scope, but if you have missing Terraform features, please report them on the repo so we can know and decide what to do

EDIT OK, computer says NO!!!! - This indicates that your device is using RMRR (opens new window). Intel IOMMU does not allow DMA to these devices (opens new window)and therefore PCI passthrough is not supported EDIT 2 Could we patch the kernel too? https://github.com/kiler129/relax-intel-rmrr/blob/master/README.md#other-distros

@olivierlambert Thanks. I suspected that, but thought it was me being dumb and haven't found anything on it Thanks

@Andrew Thank you very much for your reply. This helped a lot, and I was able to get serial access to VMs configured to use the serial port.

Hi, No, it's not possible: XAPI and xl are very very different. However, you can tell us what do you need and we could help to tell if it's needed or possible in XAPI

Thank you very much @phipra : it's important to know what happened and this is really helpful for others experiencing similar issues!

@dj423 Second occurrence of kernel BUG error: [237621.042604] BUG: unable to handle page fault for address: ffff9bd9bc6c9840 [237621.049589] #PF: supervisor read access in kernel mode [237621.055044] #PF: error_code(0x0000) - not-present page I am seeing some strange errors on the host (X1), for storage devices that no longer exist on the host. e.g.: [331863.198883] print_req_error: I/O error, dev tde, sector 74842904 [332612.663953] block tdd: sector-size: 512/512 capacity: 178257920 [332612.711329] block tde: sector-size: 512/512 capacity: 251658240 [333679.019750] print_req_error: 86 callbacks suppressed [333679.019750] print_req_error: I/O error, dev tdd, sector 74924032 The storage devs on host: tdc 254:2 0 85G 0 disk tda 254:0 0 120G 0 disk tdf 254:5 0 32G 0 disk Any idea why I would see I/O errors for storage devices that are no longer on the host? I only see this on one VM on this host, all others are fine.

@olivierlambert we couldn't find a reason either. We will run more tests in the following weeks and report if we find anything of value.

@olivierlambert Those were the only messages on the log, nothing else captured on any other log file like the crit.log file or dmesg

@olivierlambert Had the same issue with a similar server. Replaced both RAM and disk but the host kept going into read-only mode. The host would run just fine when installing any other OS/hypervisor. The server model is Supermicro SYS-6028TP-HC0R

@fred974 thath is the intendended behaviour, since, it's starts the destination VM , and the source and destination have the same ip

@Andrew said in Xen-guest-tools installation problems: You can rename libxenstore.so.4.0 to libxenstore.so.4 Thanks for the info... I figured the utilities have not yet been updated, and you have confirmed.

+1 to @Andrew setup

@ThasianXi said in Installing portainer on xcp-ng: I usually use Rancher to manage K8s and I always install on its own VM. Thank you for your input I tried rancher and couldn't make head and tail of it. Also not much tutorial out there

Hi, It's not XO related but XCP-ng related

@zxcp As of right now I am assuming it is because I kill the VM shorter than normal.

@olivierlambert Thank you for your reply. (You're very active and responsive in forums. I noted your replies to Tom_LTS in his videos last year!) I actually don't think it is a huge issue right now. Xen is running, and I am able to get in and set things up via ssh into dom0 at the moment. Some of the problems I run into are just due to lack of / outdated documentation on Xen itself. I'm quite technically capable (despite being frazzled trying to get such a complex system setup going), but the stumbling blocks are the documentation on the internet, and a lack of a good venue to ask clarifying questions. It's been a while since I've used IRC and mailing lists, and that seems to be the only/best source for Xen community technical questions. I've looked into Qubes, and it seems to be compelling, but I want to try to build this path from the ground up first. If it proves to be too much hassle or is unstable and I can't get any further with it, I can always drop back and go the Qubes route. Are there any other, more modern community venues to get Xen-on-Desktop technical questions considered? I'll go as far as I can with the available online documentation, and google the exceptions as I run into them (like this one), but it would be nice to find a place where I could go to ask the questions my google-fu doesn't suffice to locate answers. Anyway, thanks again for the information/assistance! I do have plans to use XCG-ng on some of my servers once I get things all set up in the office for them.
