Virt sig会议议程纪要： 1、openEuler 20.09虚拟化特性代码已经合入，正在进行稳定性和可靠性等测试。 a) vcpu hotplug/mem hotplug/HPRE加速三个特性已经测试完成。 b) 虚拟机可信启动/安全启动/PMU NMI-Watchdog/双层调度等特性正在开展测试中; c) VMtop、ARM虚拟机支持超线程、ARM虚拟机cpu feature支持Custom三个特性尚未开展测试，正在分析及测试设计； 2、EulerRobot质量体系构建进展： a) EulerRobot已经开源，已有部分开发者参与，希望后续有更多开发者参与，共同完善和优化openEuler虚拟化质量体系。 b) crystal-ci当前存在物理机部署后卡死无法使用情况，crystal-ci团队解决中，等解决完后再进行对接。 c) openEuler下虚拟化qemu/libvirt等仓库，代码门禁已经OK，正在实现让qemu/libvirt仓库代码合入后自动化生成Patch同步到src-openEuler中便于版本rpm制作，后续代码提交将切换至openeuelr仓库。 3、openEuler 支持riscv虚拟化的进展如下，后续主要进行bugfix。 a) Qemu支持RISC-V架构的KVM； b) 支持RISC-V架构虚拟机热迁移； c) 支持vhost的ioeventfd方案； From: Chenzhendong (alex) via Virt [mailto:virt@openeuler.org] Sent: Friday, September 4, 2020 10:19 AM To: virt(a)openeuler.org; dev(a)openeuler.org Cc: Zhangxiaofeng (F) <victor.zhangxiaofeng(a)huawei.com> Subject: [Virt] 【Meeting Notice】Virt sig meeting Time: 2020-09-04 14:30-15:30 Virt sig会议议程： 1、openEuler 20.09 虚拟化特性进展 alexchen 2、EulerRobot质量体系构建进展 kuhnchen 3、openEuler RISC-V虚拟化支持进展 Jiangyifei ------- 原始邮件 -------- 发件人： Meeting Book <uMeeting(a)huawei.com<mailto:uMeeting@huawei.com>> 日期： 2020年9月4日周五 10:03 收件人： zdchenhn(a)163.com<mailto:zdchenhn@163.com> 主题：【Meeting Notice】Virt sig meeting Time: 2020-09-04 14:30-15:30 Topic Virt sig meeting Time 2020-09-04 14:30-15:30((UTC+08:00)Beijing) Join Conference Join (External) >><https://welink-meeting.zoom.us/j/258690350> Meeting ID 258 690 350 Convener 陈振东 Tips: Dial the access number to join conference<http://app.huawei.com/eshare/voiceMeetings> 注：仅支持部分国家和地区。( Only some countries and regions are supported.) 如果加入会议提示“会议已结束或会议号不存在”，请在官网下载最新版本入会。立即下载<https://zoom.us/download> If a message is displayed, indicating that the meeting has ended or the meeting ID does not exist, download the latest meeting client and try again.Download<https://zoom.us/download>
