<BODY>Thank you for the info about hugepages and hv_vapic.<br><br>As for my problem, it seems to be the virtio-scsi driver. I booted with "-hda <file>" and had no hangs. I should have tried earlier, especially since I was suspecting the disk already...<br>Which version of the scsi driver are people using for windows10?<br>I first installed version 0.1.112 (which was the latest at the time of install) and am now trying version 0.1.102 (the stable version), but these are win8 drivers as the iso doesn't seem to include win10 drivers, and I have had no hangs yet (even through a radeon update). I'll stick with those and see how it goes, unless someone can recommend a better version.<br>And now, on to the last problem, sound! I'll start a new thread.<br><br>Cheers,<br><br>-- <br>Guillaume<br><br><br>---- Message d'origine ----<br>

<div dir="ltr"><div>It's possible it's the IO. I had similar issues with GTA V in a VM, where its large amounts of IO, due to the game's streaming geometry and textures against my iSCSI disk, got everything in a tizzy, altho it were freezes of a few seconds only. I solved it by using iothreads.</div><div><br></div><div>As far as hugepages go, your kernel is recent enough for transparent hugepages, so you'll be using 2MB hugepages already.</div><div><br></div><div>In regards to the CPU flags, ditch hv_vapic. You have a Haswell, with APICv, which has less overhead in KVM.</div><div><br></div><div>-mg</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Feb 26, 2016 at 8:32 PM, <span dir="ltr"><<a href="mailto:gui-gui@netcourrier.com">gui-gui@netcourrier.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><u></u>
<div>Hello,<br><br>Here is my setup:<br>CPU: i5-4460<br>GPU: R9 290<br>MB: Asrock H97M-ITX<br>Host OS: Archlinux running linux-ck 4.3.6 (but same problem with linux 4.4)<br>Guest OS: Windows10 Education<br>Mouse and keyboard are shared with synergy.<br>The script I use to launch the VM is attached.<br><br>I can boot the VM fine most of the time. However, after a while, the VM stops responding. By this, I mean I can still move the mouse on the screen (so network and graphics seem to be working, but the programs inside the VM stop working and nothing happens when I type or click. My guess is either the disk (virtio scsi) or the cpu (-cpu host,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time)<br>How can I troubleshoot this?<br>Which steps could I try to solve the problem?<br>Writing this, I realise I haven't setup hugepages, do hugepages have a chance of solving this?<br><br>Cheers,<br><br>Guillaume<br></div>
