RE: 10.2-RELEASE guest in Hyper-V boot failed.

2015-08-17 Thread Wei Hu

What is your Hyper-V version, 2012R2, 2012 or earlier? UDP offloading is not working Properly on 2012 and earlier Hyper-V. I committed a patch r286058 to 10.2 release branch on July 30th to disable UDP offloading on these releases. It might not be in RC2, should be in the upcoming RC3. Also

MSR accesses that slows down the hypervisor/host

2020-09-16 Thread Wei Hu via freebsd-virtualization
Hello, There are couple AMD processor related MSRs which are being accessed in FreeBSD. #define MSR_AMDK8_IPM 0xc0010055 #define MSR_LS_CFG 0xc0011020 We are seeing a lot of CPU time being spent in the host (Hyper-V) in handling traps when accessing these MSRs. Especially the

Hello, You can use resize option on Azure portal to increase the CPU and RAM of your VM. I believe you don't need to shut down the VM. Once you start the resizing, Azure will take care of rebooting the VM for you. The public IP will not change after the resizing. If you want to grow the disk
