Unable to create VM

[Danp]

@Sugarat If you are running XO from sources, make sure you're completely up-to-date with the latest source. There was a fix released for this earlier this week.

[Sugarat]

@Danp Thanks for that. I built the XO from source a few days back, but maybe it just missed that. I'll rebuild now and see what happens.. Thanks

[Sugarat]

I have just rebuilt the XO install, and that error has... apparently changed into a different one. Create VM operation still fails, but this time the message is:

HANDLE_INVALID(SR, OpaqueRef:NULL)
This is a XenServer/XCP-ng error

Hmph

[Danp]

@Sugarat I'm not able to replicate here. Can you check under Settings > Logs to see if there is an entry there with a detailed error log?

[Sugarat]

@Danp I tried removing the second host from the pool but it now still will not allow me to create a VM.

Ah, nice. I did not know that you could drill down into the error. The dump is as follows:

I am having the same issue which I also have two hosts which I just updated my XO from source yesterday. My log looks the exact same.

[Danp]

Seems like it is missing the SR information during VDI creation. Does this also occur with other SR types, ie: local storage?

[Sugarat]

@Danp Yes. Even when I select a local SSD SR it still happens. I'm not able to create any VM's at all, no matter which SR I am selecting.

[MathieuRA]

Hi @Sugarat. thanks for the report.
Can you try this branch: fix-handle-inavlid-vm-creation?
This should fix the issue

[Sugarat]

@MathieuRA It does indeed Sir. Thank you very much!
