VMWare ESXi 4.1
Guest: Linux kernel 2.6.32 64bit (tried older as well)
In multi-CPU virtual machine all interrupts (eth0,ata_piix) are stuck to the single CPU. When running on the pure hardware, everything is balanced ok.
Tried E1000 network driver as well as paravirtualized VMXNET3.
Any suggestions? Is it impossible to get a normal irq affinity in the virtualized environment?
