But the Storage Read and Write M/s looking fine... I don't get it Any toughts? From: users-bounces@ovirt.org <users-bounces@ovirt.org> On Behalf Of Thomas= Fecke Sent: Dienstag, 17. April 2018 10:58 To: users@ovirt.org Subject: [ovirt-users] Performance Issue Hey Guys, We Deploy a lot of Templates. We got our Training Environment build in Ovir= t. Our Problem - when we Deploy the Same Template. The VM=B4s getting slower e= very Time we deply a new VM from that Template. And I really don't know why. RAM locking good - CPU and Network looking goo= d. But it take about 15 Minute to create a new Template based VM - normaly it = takes about 30 Seconds. I checked nload and the Interface traffic - but its not really high. Can someone explain why its getting so slow and how to troubleshoot? --_000_1c37c0b84a77482a9b93ca8b0cf1ba3bDR1XEXCH01Besetcorp_ Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Diso-8859-= 1"> <meta name=3D"Generator" content=3D"Microsoft Word 15 (filtered medium)"> <style><!-- /* Font Definitions */ @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4;} @font-face {font-family:"Calibri Light"; panose-1:2 15 3 2 2 2 4 3 2 4;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0cm; margin-bottom:.0001pt; font-size:11.0pt; font-family:"Calibri",sans-serif;} a:link, span.MsoHyperlink {mso-style-priority:99; color:#0563C1; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:#954F72; text-decoration:underline;} p.msonormal0, li.msonormal0, div.msonormal0 {mso-style-name:msonormal; mso-margin-top-alt:auto; margin-right:0cm; mso-margin-bottom-alt:auto; margin-left:0cm; font-size:12.0pt; font-family:"Times New Roman",serif;} span.EmailStyle18 {mso-style-type:personal; font-family:"Calibri",sans-serif; color:windowtext;} span.EmailStyle19 {mso-style-type:personal-reply; font-family:"Calibri",sans-serif; color:#1F497D;} .MsoChpDefault {mso-style-type:export-only; font-size:10.0pt;} @page WordSection1 {size:612.0pt 792.0pt; margin:72.0pt 72.0pt 72.0pt 72.0pt;} div.WordSection1 {page:WordSection1;} --></style><!--[if gte mso 9]><xml> <o:shapedefaults v:ext=3D"edit" spidmax=3D"1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext=3D"edit"> <o:idmap v:ext=3D"edit" data=3D"1" /> </o:shapelayout></xml><![endif]--> </head> <body lang=3D"EN-US" link=3D"#0563C1" vlink=3D"#954F72"> <div class=3D"WordSection1"> <p class=3D"MsoNormal"><span lang=3D"DE" style=3D"font-size:10.0pt;color:#1= F497D;mso-fareast-language:EN-GB">Okay,<o:p></o:p></span></p> <p class=3D"MsoNormal"><span lang=3D"DE" style=3D"font-size:10.0pt;color:#1= F497D;mso-fareast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB">it seems to be that the Storage IO is the Problem = 211; every Write and Read Process takes a lot of time<o:p></o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB">Sometimes the copy Job stops with 0/Byte and the traf= fic goes up and down like a mountain.<o:p></o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB">But the Storage Read and Write M/s looking fine…= ; I don’t get it<o:p></o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB">Any toughts?<o:p></o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;color:#1F497D;mso-fa= reast-language:EN-GB"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span style=3D"color:#1F497D"><o:p> </o:p></spa= n></p> <div> <div style=3D"border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm = 0cm 0cm"> <p class=3D"MsoNormal"><b>From:</b> users-bounces@ovirt.org <users-bounc= es@ovirt.org> <b>On Behalf Of </b>Thomas Fecke<br> <b>Sent:</b> Dienstag, 17.
