** Description changed:
+ [SRU justification]
+
+ Impact : As Microsoft expands its public cloud offering it may need to
+ utilize additional MAC address prefixes. If a user launches a Cloud
+ instance when the MAC address is from a Microsoft MAC address that is
+ not in the exclusion list, eth0 is persistantly named for the first NIC
+ seen. If a user rebundles, or the machines has its MAC address changed,
+ it will lose network connectivity.
+
+ Fix : Add Microsoft provided and requested MAC addresses to the Hyper-V
+ list of excluded MAC addresses for peristent naming.
+
+ Test Case :
+ - Launch Hyper-V VM with MAC address in each of the ranges
+ - Install updated Udev/systemd
+ - Delete any existing udev rule
+ - Reboot and confirm that no new UDEV rule was added
+
+ Regression : None expected.
+
+ [ORIGNIAL BUG REPORT]
+
Currently /lib/udev/rules.d/75-persistent-net-generator.rules includes
the following ignored MAC prefix for Hyper-V:
# ignore Hyper-V virtual interfaces
ENV{MATCHADDR}=="00:15:5d:*", GOTO="persistent_net_generator_end"
As Microsoft expands its public cloud offering it may need to utilize
additional MAC address prefixes. In addition to 00:15:5d, please add
the following Microsoft-owned MAC prefixes to this list:
- 00-03-FF Microsoft Corporation
- 00-0D-3A Microsoft Corp.
- 00-1D-D8 Microsoft Corporation
- 00-12-5A Microsoft Corporation
- 00-17-FA Microsoft Corporation
- 00-22-48 Microsoft Corporation
- 00-25-AE Microsoft Corporation
- 00-50-F2 MICROSOFT CORP.
- 28-18-78 Microsoft Corporation
- 50-1A-C5 Microsoft
- 60-45-BD Microsoft
- 7C-1E-52 Microsoft
- 7C-ED-8D MICROSOFT
