[edk2-devel] spurious CI failures

Wed Dec 22 22:45:11 UTC 2021

I agree that building QEMU from sources is another option.

We could also consider adding QEMU to the nuget feed we use for other tools, so we avoid the current server’s perf issues.

I do find it weird that Chocolatey is taking 45 minutes to install Qemu. Is this normal? I've never used Chocolatey but I've used plenty of package managers and none have ever taken this long to install something.

Maybe it's Azure CI's problem?

Anyway, is it not possible to cross-build qemu, as detailed in https://wiki.qemu.org/Hosts/W32#Cross_builds_2, in order to avoid any package manager issues? In the case that it's the package manager's problem.

Hi Pedro,

Thanks for the link to the log.  I agree that log shows the choco install is very slow and timeout out after 45 minutes.

choco does support a flag to specify a larger timeout (--execution-timeout).  We can try increasing a bit higher as a temp workaround.

If choco is going to be this slow, we may have to use the caching features of CI agents to cache these types of downloads
so we only need to download when a version is updated.

Hi Michael,

I was curious when I read this email this morning and I found a log: https://dev.azure.com/tianocore/edk2-ci/_build/results?buildId=36430&view=logs&j=417cab99-ad63-55d7-94dd-9898cfdbbe0e&t=5e8e03ff-365b-5151-1b77-4c25d18d4964
It looks like Chocolatey is taking way too long to download/install Qemu (it's taking more than 2700 seconds).

Best regards,
Pedro

Hi Ard,

Can you point me at some PRs that have this in their log?

Thanks,

Mike
