Xen orchestra VM Console broken?
I don't know if this helps:
most of my VMs are Windows. There are a few Linux, Centos 7+, Rocky, and Ubuntu 18.
the production XO I use, is behind an Apache reverse proxy, using https. The temporary one, is just XO, using http on 8080. Looks like all of these are PVHVM, (so, HVM?) it claims. Both of these XO's are VMs on the same host, and the other hosts are on the same subnet, but some are on a different VLAN. There are also a number that are in a co-location facility, connected via a point to point fiber link, on a different VLAN, but all behind our edge router.
Console working: XCP 8.1, XS 7.1
Console not working: XCP 7.6 - I can't say for sure that these have any updates applied, though.
@stormi at least it failed on 7.1CU2 installed this morning.
I implemented a fallback not checking the version, but catching the specific error message and going back to the old method
@bberndt are you able to test the fix ?
@florent I see that the issue is still open, but looks like PR https://github.com/vatesfr/xen-orchestra/pull/6191 was merged so i assume it's not WIP anymore? Just wanted to let you know that some of the changes in that PR before merge made the initial fix non functional. Tested with installation from latest master branch commit.
Errors in browser have changed slightly:
Failed when connecting: Failed to connect to server ( (code: 1005)) util.js:44:54 Error util.js:44 _fail rfb.js:578 f rfb.js:233 onclose websock.js:305

XO doesn't log anything related to fallback method, just a normal
console proxyINFO message. Host still gives the same
Failure "ws_proxy: not implemented"error and seems that the fallback to TCP doesn't happen and console doesn't open. Still works for PV guests as it did before.
@ronivay hi , something should not have worked as intended, I'm working on it. Your server is a 7.6 ?
yeah it’s 7.6 i see this with
@ronivay hi, can you test this branch
fix_console_bisbefore we merge it?
thank you for your report
@florent thanks, yeah this seems to fix it again.
Updated to Master build, a66ae, xo-server 5.92.0, xo-web 5.96.0.
Consoles seem to work fine again.
