Re: [ovirt-users] Fwd: Re: ***UNCHECKED*** Re: kvm vcpu0 unhandled rdmsr

Hi, has anybody a last tip. Now the third installed Windows Server 2012 R2 VM is damaged and I will move tomorrow my host back to VMWare and leave oVirt.

In /proc/cpuinfo I see "nx" in the flags list, the full list is on the and of the mail. Is it possible that this problem destroy the Windows Server 2012 R2 VM? Now I start the third installation, hopefully this time it will not get damaged. If it fails again I have to use another virtualization provider and leave oVirt, and I was so happy to leave VMWare :°( This is the command line for a VM (got with ps aux ...): /usr/libexec/qemu-kvm -name srv02 -S -machine pc-i440fx-rhel7.2.0,accel=kvm,usb=off -cpu Westmere -m size=2097152k,slots=16,maxmem=4294967296k -realtime mlock=off -smp 1,maxcpus=16,sockets=16,cores=1,threads=1 -numa node,nodeid=0,cpus=0,mem=2048 -uuid 6765fd03-ac0d-49ea-b8ba-cf10c60d3968 -smbios type=1,manufacturer=oVirt,product=oVirt Node,version=7-2.1511.el7.centos.2.10,serial=39343937-3439-5A43-3135-353130324542,uuid=6765fd03-ac0d-49ea-b8ba-cf10c60d3968 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-srv02/monitor.sock,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=2016-04-03T21:24:06,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -boot strict=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x4 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 -drive if=none,id=drive-ide0-1-0,readonly=on,format=raw,serial= -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -drive file=/rhev/data-center/00000001-0001-0001-0001-00000000033d/4443edf0-54aa-4ef5-84c2-a433813f304a/images/f596f9a8-c6c4-41b8-b547-7f83829807fe/5028abbd-35c8-4dcd-95a0-3d0c61dfc2b7,if=none,id=drive-virtio-disk0,format=raw,serial=f596f9a8-c6c4-41b8-b547-7f83829807fe,cache=none,werror=stop,rerror=stop,aio=threads -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=30,id=hostnet0,vhost=on,vhostfd=31 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:01:57,bus=pci.0,addr=0x3 -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channels/6765fd03-ac0d-49ea-b8ba-cf10c60d3968.com.redhat.rhevm.vdsm,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev socket,id=charchannel1,path=/var/lib/libvirt/qemu/channels/6765fd03-ac0d-49ea-b8ba-cf10c60d3968.org.qemu.guest_agent.0,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=org.qemu.guest_agent.0 -chardev spicevmc,id=charchannel2,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=3,chardev=charchannel2,id=channel2,name=com.redhat.spice.0 -spice port=5904,tls-port=5905,addr=0,x509-dir=/etc/pki/vdsm/libvirt-spice,seamless-migration=on -device qxl-vga,id=video0,ram_size=67108864,vram_size=33554432,vgamem_mb=16,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x7 -msg timestamp=on Here are the full flags list: 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 rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm arat epb pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid cqm xsaveopt cqm_llc cqm_occup_llc On 04/04/16 08:52, Yaniv Kaul wrote: > > > On Sun, Apr 3, 2016 at 10:07 PM, gregor <gregor_forum(a)catrix.at > <mailto:gregor_forum@catrix.at>> wrote: > > Update: The problem occur when a VM reboots. > When I change the CPU Type from default "Intel Haswell-noTSX" to > "Westmere" the error is gone. > > > The error ""kvm ... vcpu0 unhandled rdmsr ..." is quite harmless. > I assume you are running the latest qemu/kvm packages. > Can you ensure NX is enabled on your host? > In any case, this is most likely a qemu/kvm issue - the command line of > the VM and information regarding the qemu packages and host versions > will be needed. > Y. > > > > But which CPU type is now the best so I don't lose performance. > > Host CPU: Intel(R) Xeon(R) CPU E5-2603 v3 @ 1.60GHz > > regards > gregor > > On 03/04/16 20:36, gregor wrote: > > Hi, > > > > on one Host I get very often the message > > > > "kvm ... vcpu0 unhandled rdmsr ..." > > > > When this occurs some VM's are stuck.
