I've changed my old laptop with a new one but I don't understand why using on both virt-manager the
qemu-system-x86 on new one takes 100% of CPU when run a vm, while on old one not.
has this output:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 69 Stepping: 1 CPU MHz: 754.000 BogoMIPS: 5187.74 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 4096K NUMA node0 CPU(s): 0-3
While in my old PC it just uses 15%-30% of the CPU. I've also actived the kvm from the BIOS but nothing changes: it continues to use 100%.
The top command gives me:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3410 libvirt+ 20 0 3641892 902428 10332 S 101,4 11,2 1:03.36 qemu-system-x86
How should I proceed?
