Re: [PATCH] KVM: VMX: Fix race between pending IRQ and NMI
Jan Kiszka wrote: But I think I see a bigger issue - if we inject an regular interrupt while another is pending, then we will encounter this problem. Looks like we have to enable the interrupt window after injecting an interrupt if there are still pending interrupts. Yeah, probably. I'm just wondering now if we can set exit-on-interrupt-window while the vcpu state is interruptible (ie. _before_ the injection). There is some entry check like this for NMIs, but maybe no for interrupts. Need to check. Turns out it's not necessary, since the guest eoi will cause an exit and allow the code to request an interrupt window. I've added an apic test program so we can track these issues (user/test/x86/apic.c). -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain. -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Jiajun Xu (jiajun) Assigned to: Nobody/Anonymous (nobody) Summary: NFS copy makes guest network unstable Initial Comment: The NFS network of KVM guest is very unstable. When we copy a 600M file to the guest by NFS mount. The guest's network will down after finishing at about 500M size. Then, guest's network is down. Host also can not use ping or scp. And sometimes, host also complains: ping: sendmsg: No buffer space available. I see memory by 'free', there is only 69MB free (While totally 8GB on the machine!). Using scp to copy file can not reproduce it. This issue is very easy to be reproduced (50%). Reproduce steps: 1. Create a guest and config NFS sharing folder on it 2. Mount the nfs folder to local folder --- /media 3. cp xxx /media 4. After some time, guest network is down -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=893831aid=2327497group_id=180599 -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

kvm kernel backtrace 2.6.27.3 using kvm 78 userspace
Hello. I just noticed that my dmesg had been flooded with backtraces, appearing to be of KVM origin. I realize that my kernel is tainted, and slightly outdated, however, i just wanted to drop the log here in case it might be useful, but feel free to completely ignore it :) i am not subscribed to the kvm list, so please cc me in case you need further info.. my entire dmesg was flooded with backtraces looking practically identical to this one, so i will only paste a few of them, however, should you want more(though from a quick look they appear identical), i can put online the complete log kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 [ cut here ] WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: PW 2.6.27.3 #1 Call Trace: [80235c84] warn_on_slowpath+0x64/0xb0 [a0899c01] paging64_gva_to_gpa+0x21/0x50 [kvm] [a088cc09] gfn_to_hva+0x9/0x70 [kvm] [a088ccd1] kvm_read_guest_page+0x61/0x70 [kvm] [a088cd28] kvm_read_guest+0x48/0x80 [kvm] [a08931ae] load_guest_segment_descriptor+0x6e/0xb0 [kvm] [a0893133] kvm_queue_exception_e+0x63/0x70 [kvm] [a08941de] kvm_task_switch+0x2ee/0x9f0 [kvm] [a088ed4c] ioapic_service+0x1ec/0x340 [kvm] [804b2af7] __down_read+0x17/0xa6 [a0893566] kvm_arch_vcpu_ioctl_run+0x266/0x6f0 [kvm] [a088c502] kvm_vcpu_ioctl+0x2b2/0x480 [kvm] [8022ee76] try_to_wake_up+0xf6/0x1b0 [8022ba4a] __wake_up_common+0x5a/0x90 [8022bea3] __wake_up+0x43/0x70 [802556ff] wake_futex+0x1f/0x30 [80257961] do_futex+0x881/0xa70 [a08b2ca0] handle_io+0x0/0x60 [kvm_intel] [802a0f46] vfs_ioctl+0x36/0xb0 [802a0f3f] vfs_ioctl+0x2f/0xb0 [802a124b] do_vfs_ioctl+0x28b/0x2f0 [802a1351] sys_ioctl+0xa1/0xb0 [8020bacb] system_call_fastpath+0x16/0x1b ---[ end trace dc61957677c4cb77 ]--- kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 [ cut here ] WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: PW 2.6.27.3 #1 Call Trace: [80235c84] warn_on_slowpath+0x64/0xb0 [a0899c01] paging64_gva_to_gpa+0x21/0x50 [kvm] [a088cc09] gfn_to_hva+0x9/0x70 [kvm] [a088ccd1] kvm_read_guest_page+0x61/0x70 [kvm] [a088cd28] kvm_read_guest+0x48/0x80 [kvm] [a08931ae] load_guest_segment_descriptor+0x6e/0xb0 [kvm] [a0893133] kvm_queue_exception_e+0x63/0x70 [kvm] [a08941de] kvm_task_switch+0x2ee/0x9f0 [kvm] [a088ed4c] ioapic_service+0x1ec/0x340 [kvm] [804b2af7] __down_read+0x17/0xa6 [a0893566] kvm_arch_vcpu_ioctl_run+0x266/0x6f0 [kvm] [a088c502] kvm_vcpu_ioctl+0x2b2/0x480 [kvm] [8022ee76] try_to_wake_up+0xf6/0x1b0 [8022ba4a] __wake_up_common+0x5a/0x90 [8022bea3] __wake_up+0x43/0x70 [802556ff] wake_futex+0x1f/0x30 [80257961] do_futex+0x881/0xa70 [a08b2ca0] handle_io+0x0/0x60 [kvm_intel] [802a0f46] vfs_ioctl+0x36/0xb0 [802a0f3f] vfs_ioctl+0x2f/0xb0 [802a124b] do_vfs_ioctl+0x28b/0x2f0 [802a1351] sys_ioctl+0xa1/0xb0 [8020bacb] system_call_fastpath+0x16/0x1b ---[ end trace dc61957677c4cb77 ]--- kvm_handle_exit: unexpected, valid vectoring info and exit reason is 0x9 [ cut here ] WARNING: at arch/x86/kvm/x86.c:185 kvm_queue_exception_e+0x63/0x70 [kvm]() Modules linked in: tun ext3 jbd mbcache usb_storage cryptomgr cbc aes_x86_64 aes_generic dm_crypt dm_mod crypto_blkcipher sha256_generic crypto_algapi coretemp it87 hwmon_vid hwmon snd_seq kvm_intel kvm fuse nvidia(P) snd_usb_audio snd_hda_intel snd_usb_lib snd_rawmidi snd_seq_device snd_pcm snd_timer snd_hwdep psmouse thermal ehci_hcd rtc snd ohci1394 ieee1394 soundcore i2c_core processor snd_page_alloc r8169 button Pid: 20168, comm: kvm Tainted: PW 2.6.27.3 #1 Call Trace: [80235c84] warn_on_slowpath+0x64/0xb0
