https://bugzilla.kernel.org/show_bug.cgi?id=198821 Bug ID: 198821 Summary: Intermittent hang in KVM with Windows 10 Guest Product: Virtualization Version: unspecified Kernel Version: 4.14.0-041400-generic Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: dan@xxxxxxxxxx Regression: No I'm running into an issue with KVM virtualisation of Windows 10. After some minutes of running the guest, it will become entirely unresponsive. This happens in kernel version 4.13 as well. Sometimes it happens immediately, sometimes it happens after several minutes from booting. Incidentally, I just booted the VM now and it hung before I could login. htop suggests that the qemu thread is blocked on IO, although this is not consistent - sometimes CPU usage will be stuck at 100% over two cores, sometimes one, and sometimes it will hang with no CPU usage. I'm new to KVM virtualisation so I'm not sure what relevant information you need, or how to get it.. Here's the command string to qemu; -name guest=win10,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-6-win10/master-key.aes -machine pc-i440fx-artful,accel=kvm,usb=off,vmport=off,dump-guest-core=off -cpu Westmere,vme=on,ss=on,pclmuldq=on,vmx=on,pcid=on,x2apic=on,tsc-deadline=on,hypervisor=on,arat=on,tsc_adjust=on,pdpe1gb=on,rdtscp=on,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff -drive file=/usr/share/OVMF/OVMF_CODE.fd,if=pflash,format=raw,unit=0,readonly=on -drive file=/var/lib/libvirt/qemu/nvram/win10_VARS.fd,if=pflash,format=raw,unit=1 -m 32768 -realtime mlock=off -smp 12,maxcpus=24,sockets=2,cores=6,threads=2 -uuid 0c8ac29b-9c58-4eb0-be1d-ad08e8f7a26f -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-6-win10/monitor.sock,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -global kvm-pit.lost_tick_policy=delay -no-hpet -no-shutdown -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -boot strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x5.0x7 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x5 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x5.0x1 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x5.0x2 -device ahci,id=sata0,bus=pci.0,addr=0x6 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x7 -drive 'file=/home/dan/VirtualBox VMs/fbn-dev-win10/fbn-dev-win10.vdi,format=vdi,if=none,id=drive-sata0-0-0' -device ide-hd,bus=sata0.0,drive=drive-sata0-0-0,id=sata0-0-0,bootindex=1 -netdev tap,fd=26,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:e2:bb:7a,bus=pci.0,addr=0x3 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -chardev spiceport,id=charchannel1,name=spice-port -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.1 -device usb-tablet,id=input0,bus=usb.0,port=1 -spice port=5900,addr=127.0.0.1,disable-ticketing,image-compression=off,seamless-migration=on -device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vram64_size_mb=0,vgamem_mb=16,max_outputs=1,bus=pci.0,addr=0x2 -device qxl,id=video1,ram_size=67108864,vram_size=67108864,vram64_size_mb=0,vgamem_mb=16,max_outputs=1,bus=pci.0,addr=0x9 -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbredir -device usb-redir,chardev=charredir0,id=redir0,bus=usb.0,port=2 -chardev spicevmc,id=charredir1,name=usbredir -device usb-redir,chardev=charredir1,id=redir1,bus=usb.0,port=3 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -msg timestamp=on Some machine specs; $ cat /proc/cpuinfo # 23 of these processor : 23 vendor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz stepping : 2 microcode : 0xf cpu MHz : 2659.992 cache size : 12288 KB physical id : 1 siblings : 12 core id : 10 cpu cores : 6 apicid : 53 initial apicid : 53 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm pcid dca sse4_1 sse4_2 popcnt aes lahf_lm tpr_shadow vnmi flexpriority ept vpid dtherm ida arat bugs : bogomips : 5319.92 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: Please let me know if you need anything else.
