Hi Marcelo, for instance Standard_A2_v2 here, it looks like we're not using for SRU testing anymore, so I will take 5.0.0-1032.34 Bionic Azure kernel for example, the cpu hotplug test from kernel selftest will report that the following instances got some CPU offlined by default: * Standard_DS15_v2 (https://pastebin.ubuntu.com/p/Ppw9WQSNMH/) * Standard_DS4_v2 (https://pastebin.ubuntu.com/p/Bms5XF4Qxk/) * Standard_DS5_v2 (I will skip pasting outputs) * Basic_A2
Not sure if this a by-design result (maybe it's how Azure cloud manage its resource?) But I think this not why the test has failed on them, as it can pass on some other instances even with some CPU offlined by default: * Standard_B1ms (only one cpu, test skipped https://pastebin.ubuntu.com/p/xzJb3jVY3g/) * Standard_D48_v3 (test passed, https://pastebin.ubuntu.com/p/T7bPKNZ7Pw/) * Standard_F32s_v2 (test passed, https://pastebin.ubuntu.com/p/J68CvkZb4Y/) You can check the test report for azure here http://10.246.72.46/trackers.html (internal link) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-azure in Ubuntu. https://bugs.launchpad.net/bugs/1831543 Title: Standard_A2_v2 Azure instance will have CPU in offline state Status in ubuntu-kernel-tests: New Status in linux-azure package in Ubuntu: New Bug description: This needs to be investigated to see if it's been disabled intentionally.
